drop-upload test for non-existent local dir separately from test for non-directory...

A candidate patch for #1429 has a bug when it is using FilePath.is_dir() to detect whether the configured local dir exists and is a directory. FilePath.is_dir() raises exception, instead of returning False, if the thing doesn't exist. This test is to make sure that DropUploader.__init__ raise different exceptions for those two cases.
