app dist needs to be cleaned after a workspace switch `aio app use`

### Expected Behaviour

Running `aio app use` to switch to another workspace and then `aio app run | aio app build | aio app deploy` should build and deploy in the new target.

### Actual Behaviour

```
ℹ No actions built for 'dx/excshell/1'
ℹ No frontend or a build already exists, skipping frontend build for 'dx/excshell/1'
ℹ No actions deployed for 'dx/excshell/1'
✔ Deploying web assets for 'dx/excshell/1'
```
The web assets are actually deployed, but even they are probably incorrect because they were not rebuilt for the new workspace.
