invalid_keys.py: Test compositied nodes are reported back usefullydanielsilverstone-ct/fix-node-provenance

Test that we get the correct provenance from a node which has
been compositied.

This tests asserts that if we forget to include one of the
local plugin's essential keys, we fail and see the appropriate
error message.
