Complete tests for `vm.Execute`

[Lawliet-Chan]

As https://github.com/NethermindEth/juno/blob/main/vm/vm_test.go#L134, your test for vm.Execute() is filling nil transaction into it. I think we should add more tests with real cairo contracts to complete it. We make a test repo for this vm.Execute() https://github.com/reddio-com/testbot/tree/thix/add_declare BUT get some bug, could u pls tell me how to fix it?

You can build and test it with README. Then you will get the error as follows:

panic: invalid type: null, expected a sequence at line 1 column 4

goroutine 1 [running]:
main.main()
