iOS7 Table View cell scrolling fix: https://github.com/kif-framework/KIF/issues/326
Set the text of a UISearchBar if a keyboard character can't be found.

This seems to be related to #263. KIFUITestActor already manually sets the text
in a UITextField and a UITextView when a character cannot be found, so
this change includes UISearchBar as a view whose text can be manually
set if needed.
