No need for the extra join since membership is built-in to current_state_events (#15731)

Browse Source 
This helps with the upstream `is_host_joined()` and `is_host_invited()` functions.

`membership` was added to `current_state_events` in https://github.com/matrix-org/synapse/pull/5706 and forced in https://github.com/matrix-org/synapse/pull/13745
