Add a function to get recipients under more span.

Currently, RecipientEditTextView only allows access to selected
recipients, where hidden recipients under +1 (more chip) span are not
included.

Added function, getAllRecipients(), allows getting all the recipients,
selected and hidden so that callers can make use of already loaded
information from chips.
