Tests + e2e: fixed breaking tests

Since lots of changes have been made, most tests were broken. This PR fixes
most of them and disable some that will be enabled once the new FileView
is ready.

This allows to fix some bugs:
- closing a tab would trigger an out of bound mobx read
- Overlay component would not get active after it has been activated once
- React-Virtual would render every items because its ref was incorrectly set
