Bug 409853

on my desktop workstation, akonadi is configured to use a central mysql database on a database server (~ is on NFS, 'nuff said). Since 5.11.3 akonadi dies after 
the first setup, due to dbinitializer in this configuration not realizng that the DB is already initialized.

STEPS TO REPRODUCE
1. do a fresh akonadi configuration using a mysql database on a different machine via tcp/ip, set up some akonadi agents as usual - imap, webdav calendar, google, etc
2. wait for akonadi to fill with data
3. log out (and maybe restart your desktop workstation to make sure all akonadi processes are stopped)
4. log back in


OBSERVED RESULT
akonadiserver is not running

EXPECTED RESULT
akonadiserver should be running

Observe the dbinitializer trying to add a column to a table where that column already exists.
