This variable isn't used anymore, remove.

Done.

Remove this variable and just pass shortcut_info->url into the

OPEN_DISMISS and OPEN are no longer triggered by anything right? Can you
annotate that this is the case in
chrome/browser/android/webapk/webapk_metrics.h? Don't remove them from the enum
since that will mess up the histograms backend.
