Add option to retry sending a file when peer is unjoinable
On Android (6.0, version 20201130-02) there is no specific option to retry sending a file. I noticed that on GNU/Linux there actually is a retry button from context clicking on the message. However, I cannot find that option in the Android app. The easiest way for now is clicking on "Share file", choosing Jami and finally selecting once again the same peer/contact, though there would be easier to have a precise "retry" button/option.
