Disable msc2716 until Complement update is merged

Disable msc2716 tests until both the Complement and Synapse PRs
are merged.

Currently #10432 is merged
but is still open matrix-org/complement#168
which relies on the changes.

Unfortunately, we would run into this situation if either side was merged too.
