[FEATURE] Non-degrade testing for network upgrades

[YoshihitoAso]

1. Is your feature request related to a problem? Please describe.

• When upgrading ibet Network, we would like to add a test to guarantee that no degrading has occurred in the processing of smart contracts.

2. Describe the solution you'd like

For a simple contract, we will add a test that checks the following

• Deploy on the old version network.
• Deploy on the new version network.
• Verify the call and transaction of the old and new contract functions can be performed normally.
