Overview breaks if extension is disabled

[mzur]

The overview seems to break if the extension is disabled and the overview override was enabled.

pretty sure this wasn't happening, it seems like this bug happened at some point while cleaning.

You're right, this was introduced by 30c0d78462fa7ffa2dae4b44d698f03e57f5b75b. However, the reset of the workspace layout is completely valid and can't be done any other way. Maybe it's related to #180. If the overview is not reset properly, maybe it can't handle the single row workspace layout.

error log to help investigate the problem more, sounds related to #180
