completion tests: add tests for the __git_refs() helper function
Check how __git_refs() lists refs in different scenarios, i.e. - short and full refs, - from a local or from a remote repository, - remote specified via path, name or URL, - with or without a repository specified on the command line, - non-existing remote, - unique remote branches for 'git checkout's tracking DWIMery, - not in a git repository, and - interesting combinations of the above. Seven of these tests expect failure, mostly demonstrating bugs related to listing refs from a remote repository: - ignoring the repository specified on the command line (2 tests), - listing refs from the wrong place when the name of a configured remote happens to match a directory, - listing only 'HEAD' but no short refs from a remote given as URL, - listing 'HEAD' even from non-existing remotes (2 tests), and - listing 'HEAD' when not in a repository.
