Reverted getCase fix although I feel it's unrelated

Read size error is from not looking for valid string first as indicated
by Lojack.  When MelLstring is used it does not first determine if it is
a normal string and the process it as such.  It will try to read past
the buffer.  As inficated in an error reported by Arthmoor.

ModReadError: Skyrim.esm: CLMT.FNAM: Attempted to read past (13310199)
end (249371467) of file/buffer.
