    Run "git stash" and "git stash apply" before and after a dry test run. · e9c4d717

    Reason: We don't want to destroy local uncommited changes when running tests.
    
    One solution was to mock bisect_utils.GitRun -- doing that caused the course of the run to change, making it so that there were no results (since git log is used to get a list of revisions, even for the dry run). So if we want to solve this problem by mocking git, we should replace it with a fake RunGit that returns different canned values depending on what the input is.
    
    The advantage of stash/apply is that its simpler, but it's also a little bit slower than the above way.
