df: don't ignore their sigs, even if we've already seen them 

In the case of failures/disconnects between dualopend receiving the sigs
and the main man disconnecting (as can happen using the testing
disconnects), failing to forward their sigs over to lightningd can
result in the channel never progressing from DUALOPEND_OPEN_INIT
to DUALOPEND_AWAITING_LOCKIN.

Always re-relay.
