fix conversation flicker when sending on a thread w/ attachments
Conversation state hash comparison was taking attachmentsJson
into account, but that's not safe to do because it's mutable.
(conversation render re-generates that JSON string, not
guaranteed to be identical)
However, we still need attachment state comparison to reload
conversation view enough upon saving a new draft w/ attachments.
So replace simple but unsafe JSON string compare with
order-agnostic attachment URI set comparison in
getAttachmentsStateHashCode().
