pytest: fix test breakage added by d0c85033d2

By setting nLocktime to the current block, the reorg test
"test_funding_reorg_remote_lags" actually drops the funding transaction
entirely when a reorg happens.

Except the 1 in 10 cases where nLocktime is randomly set to 1-10
blocks earlier.

This implies, strongly, that we hit "restart" too often on Travis.
