So a <TemporaryDirectory> if used directly, and a <str> if used as a

The code in master has the context manager return `self.name`. This
behaviour has (based on looking at the 3.2 tag where TemporaryDirectory
was added) always been used.
It is an often overlooked fact that a context manager is free to return anything, not just itself. So
TemporaryDirectory can create the folder, return the name of the folder, and remove the folder on exit. So no need for
the "extract the name from the object" dance. Interestingly enough, that is what the docs say [1].
Pretty cool.
