[Android] Save url in enhanced bookmark edit activity correctly.

[Android] Save url in enhanced bookmark edit activity correctly.

If user edited title and url at the same time, url didn't get saved.
The reason is that we save title first, then UI is refreshed by
bookmark observer, which resets the url edit text to the original url.
