Fix: Replace outdated get1Session with getSession in setResume()

Replaced the call to the outdated native get1Session method with getSession,
resolving performance issues for TLS 1.3 session resumption. This change reduces
the setResume execution time to well under 2 seconds, meeting performance requirements.
All tests passed after the update.
