Fix closing and deleting of files in tests
A few things are fixed by this commit: - check error value returned from `fs.RemoveAll` in `removeAllTestFiles`. - Defer statements are a LIFO, and were out of order in some test functions. - The TestReaddir* funcs were failing to close some file handles. - `findNames` was opening file handles but ignoring them. Bad.
