feat(ui): New Room List filter: deduplicate_versions

[Hywan]

This patch adds the new deduplicate_versions. This new filter will filter out room versions that are outdated. Only the “active” versions are kept.

A room version is considered active if and only if:

• the room is joined and has no successor,
• the room is joined and has a successor room that is invited or knocked,
• the room is left, invited, banned or knocked.

All other rooms are filtered out.

the room is left, invited, banned or knocked.

Do you mean

the room is invited or knocked.

?

[Hywan]

No I don't mean that.

When a room is left, invited, banned or knocked, we don't see what's happening here, so we don't know if the room is tombstoned or not. Consequently, we consider this is the active version of the room. Those are cases are edge-cases to be honest.

[bmarty]

OK your right, I was thinking of the api to return the room list to the application, but this is something else here.
