Found this issue while working on my client and testing out room hierarchies.

Create a subspace in a space
Leave the subspace
Subspace is still returned in room hierarchy (which is a different issue)
num_joined_members still returns one

Rooms with no members are essentially bricked, but the member count being wrong makes it difficult to make decisions on the client side.

!admin rooms info list-joined-members does return the correct count of zero, which means the problem is in fact the cache not being invalidated.

Happy to action this. I think it should be an easy enough issue for me to dip my toes into the codebase
