Jason Rhinelander 1f03bb41b7 Test suite: add tx version hack and remove broken tests 
This adds a variable hack into loki-core that lets us disable the
transaction hard fork requirement so that the test suite can still
generate transactions under older tx rules even though the transactions
will be modern CLSAG txes.

These are sort of bastardized txes that can never occur on the proper
mainnet, but let us keep tests that apply to v2/v3 transactions even
though we can't actually generate proper v2/v3 transactions anymore.

A few tests got removed here because they are testing for old invalid
bulletproof formats that don't matter anymore because they will never be
accepted on the current chain anyway.
