add testcase for timing sensitive crossing hello channel upgrade using historical proofs

[damiannolan]

Summary

Some testcases become tricky to fit into the general pattern of table structured tests we follow within ibc-go.
This testcase will require creating an additional test function.

See thread

In a channel upgrade crossing hello scenario both parties may perform both INIT and TRY steps.
A timing sensitive case allows both parties to also perform the TRY step. Consider chainA(INIT), chainB(INIT), chainA(TRY) and chainB(TRY) - chainB(TRY) will only succeed if a historical proof is submitted of the channel state prior to chainA(TRY).
