Drop some test bits that rely on fedfind modular compose support
    
    I removed modular compose support from fedfind recently. I don't
    think we need to pull all the modular bits out of wikitcms
    itself, they're still useful to parse the old test pages. The
    inability to find the matching fedfind compose shouldn't really
    be a practical issue at this point.
