Watch mode does not work for linked remote sources

[eysi09]

Bug

Current Behavior

When running Garden in watch mode and working on a linked remote source, changes to that source are not detected by Garden. Instead you have to kill the process and run the command again.

Expected behavior

Garden should detect the changes and automatically re-run.

Reproducible example

1. Use the remote-sources example project
2. Clone one of the remotes, say garden-example-remote-sources-web-services
3. Link it with garden link source garden-example-remote-sources-web-services local/path/to/clone
4. Notice how changes to the cloned code don't trigger a watch event

Workaround

Re-run the command on changes
