[BUGFIX] Create default backend user groups without EXT:dashboard

This patch corrects the optional last step of the initial setup
process "Create default backend user groups" if EXT:dashboard is
not installed. This may be the case for a composer based
installation. Instead of silently failing the step due to the
missing column "be_groups.availableWidgets" this permission is
not written to the database.
