Cannot leave community located on a dead homeserver

[pacien]

Description

It's not possible to leave a community hosted on a homeserver which died.

The community can be hidden from the side filter panel, but will stay in the user's communities page forever.

Trying to open the community's information page to leave it displays "Failed to load +community:deadhomeserver", giving the user no way to leave the community.

Steps to reproduce

• Create a community on homeserver A
• Join this community using an account on homeserver B
• Shutdown homeserver A
• => It's now impossible for the account on homeserver B to display the community's page to leave it.

Not sure how useful it is to track it here. It is really a Synapse issue. matrix-org/synapse#5254

It's both since Riot's UI offers no way to hit the "leave community" button in such situation.
