`exp show --show -json`: `outs` does not return full path for keys
# Bug Report

<!--
## Issue name

Issue names must follow the pattern `command: 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`
-->

## Description

`exp show` output returns incomplete paths for `outs` (and maybe `deps`).

<!--
A clear and concise description of what the bug is.
-->

### Reproduce

<!--
Step list of how to reproduce the bug
-->

Demo project structure is as follow:

```yaml
stages:
  train:
    cmd: python train.py
    deps:
    - data/MNIST
    - train.py
    params:
    - params.yaml:
    outs:
    - model.pt:
        checkpoint: true
    metrics:
      - training_metrics.json:
          persist: true
          cache: false
    plots:
    - training_metrics
    - misclassified.jpg
    - predictions.json:
        template: confusion
        x: actual
        y: predicted
```

```

Notice the `"raw":` key in the outs output. I believe this should be `data/MNIST/raw`.

<!--
Example:

1. dvc init
3. Copy dataset.zip to the directory
4. dvc add dataset.zip
5. dvc run -d dataset.zip -o model ./train.sh
6. modify dataset.zip
7. dvc repro
-->

### Expected

<!--
A clear and concise description of what you expect to happen.
-->

Full paths are returns for all `deps`/`outs`.

### Environment information

<!--
This is required to ensure that we can reproduce the bug.
