Title: Fix table lock hints on SQL Anywhere

`SQLAnywherePlatform::appendLockHint()` should not throw an exception if an unknown lock mode is given but rather return the unmodified `FROM` clause instead. This is especially required for ORM to work as it passes `null` by default which currently causes SQL Anywhere platform to throw an exception.
