Reland "Do not count as paste when setIgnoreTextChangesForAutocomplet…

…e is called"

This is a reland of commit bc664c9

We cannot guarantee the pedal is offered when we type "open incog" in the
test, so test is flaky.
I think that we cannot guarantee that action button is offered, or what
action button will offer to us, so I removed the test.
Since this is a RBS bug, we can land the fix now, and add the test in a
follow up.

Original change's description:
> Do not count as paste when setIgnoreTextChangesForAutocomplete is called
>
> When AutocompleteEditText#mIgnoreTextChangesForAutocomplete is set to
> true, we should not do anything for sanitizing the text.
