lnwallet: add funding amount assertion to tests

Browse Source 
In this commit, an assertion is added to the bolt 3 commitment tx tests
that ensures that the local and remote balances add up to the expected
funding amount. Adding this assertion uncovered a borked test vector
which is also fixed in this commit.
