Core/Movement: Fix WaypointMovementGenerator ignoring EscortAI::SetEscortPaused() on Gossip Hello (#24005)

Fix WaypointMovementGenerator ignoring EscortAI::SetEscortPaused() when talking to a NPC, scheduling a 3 minutes pause on the WaypointMovementGenerator even if it was already disabled with no timer, waiting for the player to select a gossip entry to resume the movement.
