I am purposefully not deleting the resource. I am going to bring this function
back in a CL that I will post in a few hours.

We want to display this toast if the request to Google Play to install the
WebAPK times out. If the play request times out it is possible that the WebAPK
install is delayed (e.g. because play is updating) We want to avoid the
situation of a user having two homescreen shortcuts. A WebAPK shortcut and a
webapp shortcut
