Jan Mulder 42eae7e48b Mobile: simpify startup logic
When starting the mobile app, I noticed a short display of an empty
page with title "Cloud creditials" just before showing the
divelist. Simply a not nice visual effect.

This commit simplifies some logic and resolves this. As the code
in this part is fragile, this is tested for normal and clean
startup of the app, switching credentials, from no cloud to
valid account (which even nicely imports the no cloud dives:
this surprised me as I have never seen this working).
