Default Specs per thread when no specs found - confusing!

[rob-pocklington-a139759]

First, thanks for writing this library, it's a great effort.

Sometimes, for a number of reasons (browser disconnects, using xit or xdescribe) when no tests are included in the karma test suite run, and you run them using this library, it creates a default spec for each thread. This seems a little unorthodox and makes you think all tests have run successfully, unless you look at the number or the description of the test.

The lines of code are here:

 if (!hasSpecs) {
        ctx.describe('[karma-parallel] Add single test to prevent failure', function() {
          (ctx.it || ctx.specify).call(ctx, 'should prevent failing by having sucessful tests', function(){});
        });
}

See https://github.com/joeljeske/karma-parallel/blob/master/lib/karma-parallelizer.js#L151

Can I ask that we remove this behaviour if no specs are found?

This is changing the basic implementation of the test runner.
