fix(terminal): free the "[Process exited]" msg extmark #38246

Browse Source 
Problem: Since the "[Process exited]" msg is no longer part of buffer
contents, `jobstart`'s reuse of unmodified finished terminal buffers
does not clear the msg.

Solution: Delete the extmark if `term` is already closed.
