User mood list doesn't update when clicking back button

[Tyler Elston]

After searching for a mood, clicking the back button should clear the search

Steps to reproduce:

• have multiple moods with at least two different mood types
• search for one mood type
• click back button
  .. the search bar goes away but still only the searched for mood type shows
  maybe have the search clear when you click back?
