context: when force-quantum, remove lock-quantum

Browse source 
If a node (or metadata) forces a quantum, remove any nodes that
requested a lock-quantum so that we can change the quantum to the new
forced one.

This makes it possible to run jack clients with node.lock-quantum while
still allowing them to change the quantum qith node.force-quantum.
