CORDA-2134 - re-enabling ignored tests due to signature constrains non-downgrade rule (#4398)

Browse Source 
1) TwoPartyTradeFlowTests - restructured - saving transaction just after creating a state, as it's needed for the next TransactionState to be verified (for non-downgrade rule), enable more tests which were set as @Ignored, left 3 TODOs as 2 tests were slightly modified, need further investigation
2) MockService method loadContractAttachment always returns a dummy Attachment which means it has a default Contract Class Version number 1 used for signature constraints non-downgrade rule.
3) TransactionSerializationTests - added a fake transaction which created fake stated used as input state and using real (not mocked one) implementation of loadContractAttachment
