Remap CODE_REJECTED_ELSEWHERE to incoming rejected.

CODE_REMOTE_CALL_DECLINE and CODE_REJECTED_ELSEWHERE are both explicitly
documented as handling the "call rejected elsewhere" multiendpoint usecase.
Yes, they're exactly the same.  And they should be duped in the future.

Fixes: 194079457
Test: To be manually tested by test team (infeasible to development test
locally).
