Merge #888 #889

888: Correct the URL users are directed to after using setup without exposing /admin r=mergify[bot] a=Nebukadneza

In setup, users who didn’t expose `/admin` were directed to `http://127.0.0.1:8080/`, which was missing `/ui` to work.

Also, let’s help out the less apt admins by providing a copy-paste template for ssh-tunnelling.

889: Catch webmail-url empty but webmail configured and force to default r=mergify[bot] a=Nebukadneza

## What type of PR?
bug-fix

## What does this PR do?
Quite some users managed to delete the contents of the webmail-url field in
setup, which forces front into a restart loop. Catch the case where a webmail
service is configured, but url is empty — and force to default /webmail.
