Resolving stupid shaded jar problems

Having httpclient in the test scope prevented it from getting into the
compile scope, which broke the shaded jar and ended the world.
Fixing a null pointer because jaxb sucks
Actually do bean postprocessing using the environment correctly
Updating the core spring provider for the filter contexts
Initialize core context
Setting the postProcessor every time we make a new thing
Switching to copy, not to unpack
Needed to add the version of the artifact
 Have to get the file itself
Redid this test to use more repose guts

It fails :(
