StringName: fix returning dangling data from char constructor.

Browse Source 
Fixes a copy paste mistake in the `StringName(const char *,bool)` constructor,
to match the same form as the other two constrcutors.
This fixes a case where this constructor can return a dangling pointer and cause use-after-free.
