The extensionmanager tries to merge the default configuration
with the already saved one. If no configuration has been set yet,
the result of the unserialize operation is a boolean false instead
of an array and that is causing a fatal error when it tries to
merge both configurations with the ArrayUtility::flatten method
This patch adds a check that sets the current configuration
to an empty array if none exists.
