Move logic which parses intent and forceably sets the text of our search
input to onCreate(), not onResume(). onCreate() is invoked each time a
new intent is sent to open up this activity. That is, each time a new
category is opened or a new search request is received. onResume() is
called much more often than this, including when the user is directed to
a new activity and then returns to the search screen after hitting back.
In this case we don't want to remove the search query the user had and
replace it with the data in the original intent.
