Summary: __slots__ tuple modified inplace if it contains unicode name

Initial Comment:
Function _unicode_to_string() in typeobject.c
tries to copy the original tuple by asking for
a complete slice of the original tuple. This
case is special cased in tupleslice() to only
incref the original tuple. As a consequence,
the user's tuple could be modified (see
the test). 
There are also some reference leaks if an
unicode name can't be encoded with the default
codec. 
The patch fixes this and adds tests for both
cases. I also moved a comment about possible
leaks to the appropriate place.
