[FIX] mail: do not return members of channels in channel_info

This PR has 3 parts:

The members fix itself, which is necessary for performance reasons especially
at init messaging, as per described in the task.

Adding the partner name in the typing payload, because due to not knowing all
members anymore, it is necessary to properly display who is typing.

Restrict restoring scroll position only if the corresponding scroll height is
available, to make the scroll feature and particularly the corresponding tests
more robust.
