Parse recipients from RESPOND_VIA_MESSAGE correctly

UriUtil#parseRecipientsFromSmsMmsUri() will returns a comma-separated
recipients for common use so that InsertNewMessageAction#createMessage()
can create or get a conversation correctly for RESPOND_VIA_MESSAGE.
In addition, mms/mmsto schemes are added. And it includes small cleanup
intent-filters for LaunchConversationActivity.

Test: adb shell am startservice
-a android.intent.action.RESPOND_VIA_MESSAGE -d "sms:12345678,87654321"
-e android.intent.extra.TEXT "Text"
