    tests: bail early if nunit-console is not found (bgo#722565)
    
    It's not worth checking for this at configure time because
    one can build Banshee fine when having nunit libraries but
    not the runner (i.e.: in a Debian-based distro, having the
    package "libnunit-cil-dev" installed, but not the one
    named "nunit-console").
    
    But we need to check before running the tests, otherwise
    the user may get many errors (as many as the number of
    test assemblies we have), instead of just one, making it
    very clear what is missing.
