bug: deploy_syscall behavior in testing context

[notV4l]

Bug Report

Cairo version:
Latest

Current behavior:
In testing context, deploy_syscall doesn't test if a contract is already deployed at address.
Is this intended behavior ?

Expected behavior:
I'd expect a fail_syscall!(b"CONTRACT_ALREADY_DEPLOYED");
