Invalid namespaces for tests http/nodes|fact_names masking failures

The test files http/fact_names.clj and nodes.clj had incorrect namespace
declarations that were overridden in other files. This caused these tests
to be skipped and in fact mask a couple of failures.

Luckily these were testing failures only, once fixed this is all passing
again.
