Fix: Log entries are written twice
Fix: Log entries are written twice

During plugin bootstrap phase, a call to CakeLog::critical() maybe made
(due to missing plugin) when the Log engine has not been configured.

This causes entries to be written twice and a file `tmp/logs/.log`
to be created incorrectly.

Conflicts:
	Config/bootstrap.php
