Reland of [Android:WebAPK] Don't add webapp to homescreen if WebAPK install times out part 2/3

Reland of [Android:WebAPK] Don't add webapp to homescreen if WebAPK install times out part 2/3 (patchset #1 id:1 of https://codereview.chromium.org/2757563002/ )

Reason for revert:
The CL reverted was part of a two-sided CL, and the downstream part landed just before this got reverted. So the Android ToT roller bot is broken again. Let's land this CL again, so that everything goes back to green.
