Allow refreshing folder content by clicking on the folder button in the path after something has been mounted under that folder

[Karl-Philipp Richter]

Currently it is necessary to open another folder (e.g. the parent directory by clicking on the button to the left in the path) or refresh explicitly after the mount took place. After mounting e.g. on the command line a user might expect the folder content to be reloaded when clicking on the folder button on the path and there's no reason to match that expectation.

Example:

  1. go to /path/to/folder (path buttons are `path` `to` `folder`)
  2. `mount /some/thing /path/to/folder`
  3. click on the path button `folder` -> nothing happens (refresh or clicking path buttons `to` and `folder` is necessary)

The result for 3. should be:

  3. click on the path button `folder` which triggers refresh for directory content because a mount point has been added whose target matches `/path/to/folder`
