Add additional resource checks in namespace tests

Testing code for namespaces must check for existence of Project resource
in every test scenario. This is not reflected in the code.
Also, in namespace isolation scenario, there are no checks for creation
of isolated Virtual Network.
Add missing resource checks.
Also, simplify test code - no need for double namespace object creation
in the tests.
Additionally, pylint the code.
