hooks enabled: waiting lease causing a wrong state at the exporter once the previous lease ends

[evakhoni]

asking a second waiting lease request to the same exporter - then later once we release the first lease, with the exporter still in afterlease state, the client starts connection attempt prematurely, causing the exporter to switch directly from afretLease to beforeLease, then to Available, and eventually to leaseReady (notice the out of order state change!). the client receives a connection lost leaving the exporter stuck in LeaseReady.

an exporter with no hooks set does not have this behavior.
