[Asterisk-code-review] res pjsip: Fix leak of persistent endpoint references. (asterisk[13])

res_pjsip: Fix leak of persistent endpoint references.

Do not manually call sip_endpoint_apply_handler from load_all_endpoints.
This is not necessary and causes memory leaks.

Additionally reinitialize persistent->aors when we reuse a persistent
object with a new endpoint.

ASTERISK-27306
