Made a set of small test changes to avoid leaving temp files hanging around after running the test suite. First, fixed a couple of places where temp dirs were (or could be) created without later being deleted. Second, added a missing close() before unlink() since Windows raises an error on an attempt to remove an open file. Finally, in the file_uploads tests, avoided opening-by-name temporary files that we already have a descriptor for. Doing additional opens seems to run afoul of the Windows issue with deleting open files, so it generally works better to just seek back to 0 instead of calling open multiple times.
