mobile: make sure old credentialStatus is defined

In commit e76f527fe5, the scenario of switching between 2 already
VERIFIED cloud accounts was identified, which was working poorly. It
needed a restart of the app to get the new account visible.

Reason for this, was the setting of the credentialStatus to the value
of an undefined (never set) old credentialStatus. This commit makes
sure we have a defined credentialStatus, just before changing it to
the new one.

A really mini step forward, as the behavior is still not perfect. Now,
the user has to select the dive list manually, after entering
credentials of the new clould account.
