[New-bugs-announce] [issue28408] Fix redundant code and memory leak in _PyUnicodeWriter_Finish

[Xiang Zhang]

New submission from Xiang Zhang:

_PyUnicodeWriter_Finish gets 2 problems now:

1. It has two same branches handling empty strings which is redundant.

2. It may leak the inner buffer object when resize_compact fails. When resize_compact fails, the buffer object is left untouched. Then the writer itself is freed and the buffer is leaked.
