recon: add collelgnot. to stateUpdates listener

Currently, collelgnotifier is not added to the list of listener
for the state updates. As a result, during collection config update,
collection eligible check is not performed to send an event to the
pvtdatastorage.

This CR adds collelgnotifier to the list of listener.
