Consolidate UNSET_DIM handling for string offset error

Browse source 
The immediate error here is the nested indexing in write context,
the fact that it's ultimately wrapped in an unset() doesn't matter.
Same as $str[0][0] += 1 will throw "Cannot use string offset as an
array", so should this case.
