Crash When Search Text was cleared

[mattsap]

Follow the actions below to replicate the crash:

In the search bar type: "ad". Click X to clear the text. Click out of the search menu, then click on any cell after the "ad".

You'll get a list index out of bounds. My fix was to eliminate the first if statement in updateSearchResultsForSearchController and always update the tableSections and tableSectionsAndItems
