Bringing up the keyboard when a picture is the last item visible will always scroll the conversation to the bottom

Bug 7511504

The code to scroll needs to test that the tall item is the last item in
the list.

Handle null result from detectCountry. Let the onCountryDetected listener
do the work and delay setting mCountryIso. Tested getCurrentCountryIso()
by always returning null to see that the app didn't crash.

The extra space after the comma was screwing up the Chips parser and causing
the comma delimeter to be parsed as part of the number.

Don't bail back to ConversationList when we've got an empty ComposeMessageActivity.
In the case where the user has entered a recipient and followed the same
repro steps in the bug, a draft is created (see CMA's saveDraft) because
the receipient editor is open and there is a recipient. In that case, the
working message is not discarded and does not go through the escape-to-
ConversationList case. By the way, I was not able to repro the original
bug 2793874 that added this escape clause code.
