Links in non-root are not refreshed in Share by Link view

[jesmrec]

This one comes form https://github.com/owncloud/android/pull/3007#issuecomment-719426005

If any link of an item in non-root is removed from the Share by Link view, such view is not refreshed and the removed link stays there.

The reason is that the view is a filter from file list and needs to be refreshed to show the updated information. The problem can be fixed when the database migration is merged into master
