Fix handling of basedir in 'rbt patch'
Review Request #5855 — Created May 21, 2014 and submitted — Latest diff uploaded
Depending on the version of the Review Board server and the particular
repository type, the returned diffset object from the API may have no basedir,
may have a basedir of None, or may be a string. In the first two cases, we want
to normalize this to an empty string.This also handles a None repository base_path.
- Ran 'rbt patch'
- Ran unit tests.
