    proxy/tests: fix to work when neither proxy module is available
    
    automake ends up setting TEST_PROGS to " " in this case, but
    Makefile.decl was assuming that if TEST_PROGS is not empty then it
    contains actual tests, and then ended up bailing out by passing an no
    tests to gtester. Fix it to use $(strip) to get the right result.
    
    Also, drive-by automake warning fix in proxy/tests/Makefile.am
