Autofill: Fix the failures on O platform

The event sequence was changed by the previous patch
https://chromium-review.googlesource.com/c/chromium/src/+/2296487

The AUTOFILL_VIEW_EXITED is only expected on Android o platform,
and will be removed for others.

This issue wasn't uncoverred because we don't have O trybot by
default.
