[Android] Fixed assert on url bar focus change

Chromium change:
https://github.com/chromium/chromium/commit/b964b99f01113d8f0107f81cbdea03c98429e874

Add logic to track suggestions list scroll events.
This change allows us to learn how frequently our users need to
scroll the suggestions list in order to find what they are looking
for.
