all the tests assume whisk.system namespace

since it is possible to install the catalog with a different key/namespace, is there a reason the tests hardcode the namespace to whisk.system?

Start by locating the tests that hardcode the whisk.system namespace and inspect how the catalog namespace is configured. Determine whether the tests can run with an alternate key or namespace; done means the relevant tests no longer depend on whisk.system and still pass.
