lnwallet/test: reproduce test vectors in commit and htlc tx test

Browse Source 
This commit changes the verification of our code against the spec test
vectors to use a more black box approach. It exercises the channel state
machine via its external interface as much as possible, making this test
more robust. A consequence of this is that the test now runs from the
'root' data from which the test vectors are also derived, meaning that
more code is covered too.

Running from the root data is also a preparation for _producing_ test
vectors for the new anchor commitment format. This will be a matter of
changing the channel type and recording the produced commitment and htlc
txes.

Previously the success transaction was skipped during verification. With
this commit, the proper preimage insertion is carried out, allowing the
success tx to be checked too.
