When removing a contact, a XMPP client will not receive an explicit
unavailable presence stanza for the contact from the server. Because
of that Swift used to show removed contacts still with their old
presence in the Chats tab or the chat view.
With this patch, the PresenceOracle will flush all known presence
of a contact as soon as the JID is removed from the roster. An
unavailable presence will stored under the removed bare JID and
is emitted via the PresenceOracle::onPresenceChange signal.
Test-Information:
Added a unit test verifying this behavior. Tested the behavior with
two scenarios:
a) Account A and B adding each other and accepting the subscription
request. Starting a chat between A and B. After removing B in A's
account, B used to be shown as available in the chat view and the
Chats tab. With this patch B is shown as unavailable.
b) Account A and B adding each other and accepting the subscription
request. A removing B, and B removing A. After A adds B again,
B used to be shown with the old presence even before B accepted
the subscription request. This behavior is also fixed with this
patch, not showing B as online until B accepted the subscription
request.
