Remove geolocation code from open-source QuickSearchBox

This code was not tested well, used a @hidden extra to pass location
to the browser, and did not prompt the user to
opt-in to sharing location. If we want location in the open-source
QuickSearchBox in the future, we should take the code from
GoogleQuickSearchBox.
