Proposed changes

We fixed further issues. In both, backend and frontend.
We especially managed to change the behavior of email matching.
When we needed to match before the uid (where from eMail Auth Provider was stored the name), we have now a direct matching of email -> email in the token matching section of the Generic Provider.

That means that you would re-configure the Generic Providers in the token matching section.

Also, we set the "Themes to not overwrite the App Switch" as "true" by default, so moving from older Apps to the new styling should be easier.
