res_pjsip_pubsub.c: Fix AMI event list counts.

Fix the AMI PJSIPShowSubscriptionsInbound, PJSIPShowSubscriptionsOutbound,
and PJSIPShowResourceLists actions event counts.  The reported counts may
not necessarily be accurate depending on what happens.

The subscriptions count would be wrong if Asterisk ever has outbound
subscriptions.

The resource list count could be wrong if a list were added or removed
during the AMI action being processed.
