m/n/c/curator: fix panic caused by race

The starting/stopping of the respective follower/leader implementations
is not synchronized with the state event source. Thus it can happen that
requests get routed to an improper implementation. The follower
correctly rejected requests when the current state indicated that it was
a leader, but panic'ed if it was neither which is a valid state.

Reject requests when it is not a follower, not just if it is a leader.
