[Android] Fix overzealous autocomplete removal in the omnibox.

[Android] Fix overzealous autocomplete removal in the omnibox.

To work around crbug.com/273763, we were previously removing
all text after the selection end if the selection range was
entirely before the autocomplete text.

On certain keyboards, this could result in deleting new user
text that differs from the previously autcompleted text.  Now,
we only clear the text if it matches the autocompleted text.

I verified that this fix did not regress the HTC issue (tested
on 4.2.2 w/ the Sense keyboard), and it also address the
Japanese IME issue mentioned in the new bug.

PTAL

Also, this adds debugging info that I add every time I investigate one of these
issues.
