When sending a contact update we automatically added the contact,
but that resulted in the contact not being synced correctly as
`saveContact` will not trigger the side effects.
For now I have removed this behavior. Ideally we should have a single
call that handles the side effects, but for that ENS names should be
stored in messenger, so we can propagate it.
If the user deletes/leaves a group chat, the chat is set as not active.
This means that if we are re-invited to the chat it won't be shown to
the user.
This commit changes this behavior so that if we are re-invited to the
chat it is set as active again.
