Be stricter on usage of stateKey

A few places in the library dealt with state events without any notion
of state_key inside events, including StateEvent[Base] and relevant
functions in Room. A number of workarounds have been made; e.g.,
Room::setMemberState() accepted userId as a separate parameter, ignoring
the state key inside the RoomMemberEvent already passed to it, and
Room::setLocalAliases() had a bug in the initial version where the
function still tried to pass aliases in an event with an empty state
key. This commit fixes this shortcoming: StateEventBase now gets
stateKey as one more parameter, Room::Private::getCurrentState()
respects stateKey and returns properly constructed stub events, and
Room::setMemberState() gives way to a more generic Room::setState() that
works uniformly with whatever state event you pass to it.
