Unsent message stuck at the bottom of the conversation forever

[Totogro]

Describe the bug For some reason one message in a long conversation could not get through 1h30 ago (as the conversation continued) and is stuck at the bottom of the conversation forever. We are unable to remove it. (Very annoying to the point Element seems not a viable solution for regular people who expect a smooth experience.)

To Reproduce Steps to reproduce the behavior:

1. Have an unsent message (cannot be reproduced on purpose, i'm afraid...)
2. Try to remove it from a contextual (long press) menu : impossible, no option given
3. Try to restart the app : annoying message still there
4. Try to quit the room and come back with invitation : annoying message still there

Expected behavior We expected to be able to remove this message after a long click on it to get a contextual menu with an option "delete this unsent message"
