fix(cli): fix custom world deployment

[dk1a]

deployCustomWorld returns stateBlock that is at world contract creation, but that is before initialization or ownership transfer

Currently deploying a new customWorld doesn't work because ensureNamespaceOwner gets this early stateBlock and doesn't see the updated ownership

In addition to the fix I add an e2e test for a simple CustomWorld identical to the normal world, to test that deployCustomWorld works at all (you can see it fail if you revert the fix)
