I have been trying to create a simple ML pipeline. On the evaluate stage I am creating the evaluation.json file that I state in the dvc.yaml → metrics: evaluation.json. However, when running dvc metrics show the terminal doesn’t output anything. Instead running dvc metrics show --json, yields an empty json. And whe running dvc metrics show -a -v, I get this:
Hi! Do you, by any chance call metrics from non-root dir?

<!--
## Issue name
Issue names must follow the pattern `comm… and: description` where the command is the dvc command that you are trying to run. The description should describe the consequence of the bug.
Example: `repro: doesn't detect input changes`
-->
dvc metrics show doesn't output anything when called from a subdirectory of the repository.
## Description
When the pipeline described in `dvc.yaml` is stored in a subdirectory e.g. `pipeline` of the repository and it contains a stage that produces a metric file e.g. `metric.json` within this same directory, running `dvc metrics show` within this directory doesn't ouptut anything. When calling `dvc metrics show metric.json`, the displayed path for the metric is not correct. Calling `dvc metric show` from the root of the repository seems to be ok. The issue was already looked at by @pared who provided the simplified script to reproduce the behavior.

### Reproduce
<!--
Step list of how to reproduce the bug
-->
<!--
Example:
1. dvc init
2. Copy dataset.zip to the directory
3. dvc add dataset.zip
4. dvc run -d dataset.zip -o model ./train.sh
5. modify dataset.zip
6. dvc repro
-->
Run the following script:
```
#!/bin/bash
set -exu
wsp=test_wspace
rep=test_repo
rm -rf $wsp && mkdir $wsp && pushd $wsp
main=$(pwd)
mkdir $rep && pushd $rep
git init
dvc init
echo '{"metric_val": 1}' > data.json
dvc add data.json
mkdir pipeline
pushd pipeline
dvc run -d ../data.json -m metric.json -n train cp ../data.json metric.json
git add -A
git commit -am "initial"
echo "dvc metrics show in repo subdirectory"
dvc metrics show -v
echo "dvc metrics show metric.json"
dvc metrics show -v metric.json
popd
echo "dvc metrics show in repo root"
dvc metrics show -v
```
### Expected
<!--
A clear and concise description of what you expect to happen.
-->
The first call to `dvc metrics show` (in the `pipeline` subdirectory) doesn't output anything.
The call to to `dvc metrics show metric.json` (in the `pipeline` subdirectory) outputs:
```console
Path metric_val
../metric.json 1
```
The second call to `dvc metrics show` (in the repo root) outputs:
```console
Path metric_val
pipeline/metric.json 1
```
which is ok.
'-v' option only adds lines of the following form:
```console

```
### Environment information
<!--
This is required to ensure that we can reproduce the bug.

dvc was installed from repository on an Ubuntu 20.04 (WSL). I also have the same behavior on dvc installed with pip, within a conda environment on Ubuntu 20.04.
