Delete temporary string within demangler even in failure cases.
A call to demangle_template might allocate storage within a temporary
string even if the call to demangle_template eventually returns
failure.
This will never cause the demangler to crash, but does leak memory, as
a result I've not added any tests for this.
Calling string_delete is safe, even if nothing is allocated into the
