- fix a bug in profile where app would was returning directly to profile
screen after photo capture, showing updating to user but not actually saving
and broadcasting it
- adds support for offline contact request, confirmation and updates by
leveraging the :sent and :not-sent signal from status-go. Each chat
in the protocol layer uses a `resend?` field to keep track of the current
state of the contact, between `nil`, `contact-request`,
`contact-request-confirmation` and `contact-update`. There is no case
were it can be more than one case because if `contact-request` or
`contact-request-confirmation` was not sent yet `contact-update` is not
necessary as the latest contact infos will be sent with the request/confirmation
