Renamed $grp to $group in foreach loop.

Signed-off-by: Stephan Peijnik <speijnik@anexia-it.com>

Use is_null() instead of empty() when checking the return value of GroupManager::get().

Additionally, $grp was renamed to $group inside
 \OC\Group\MetaData::fetchGroups().

Updated code to reflect changes introduced to \OC\Group\MetaData.

Now that fetchGroups() does not exist anymore and getGroups() is called
directory, the 'groups' property does not exist anymore.
Instead, we now generate that array on the fly and return it from getGroups.
