Check that there are no other akonadi_control instances running as the
very first thing on startup. Previously this check would happen after
AkApplication initialization, which contains some potential race-
conditions, like rotating log files.
The situation when akonadi_control is launched multiple times can occur
on session startup, when multiple different components will attempt to
launch Akonadi if its not yet running.
