[TASK] Clean up DataMapper::convertClassNameToTableName
This removes pointless code which ends up doing strtolower(NULL).
Also make the class name argument mandatory since it does not make
sense to pass nothing or NULL and the core does not do this in any
case.
The latter change makes this mildly breaking if code relies on the
old behavior.
