Commit d38a30df (Be more user-friendly when refusing to do something because of conflict) introduced code paths to git-pull which will error out with user-friendly advices if the user is in the middle of a merge or has unmerged files.

Implement tests to ensure that git-pull will not run, and will print these advices, if the user is in the middle of a merge or has unmerged files in the index.

Notes:
    * Test that on merge conflict, git-pull will not reset conflict status,
      or modify the conflicted file.
