Fix bug related to author name in hourly stats

* Fixing a bug where, if you insert an author's name that has a space in the
  "Git commits by author per hour" option, it fails due to improper variable
  expansion. Note that the current implementation is a "greedy" one in that
  it will attempt to look for any instance of the user provided string in the
  author field
