[bug] Gulp test wasn't running server tests [closes #873]

[codydaig]

This PR fixes #873. The models were never getting loaded in the gulp tests so it was freezing on mongoose errors. This loads the models before running the server tests.

I can confirm this fixes the issue.

@codydaig It looks like the behavior between the Grunt & Gulp test tasks is slightly different. Using Gulp, it appears that the karma task is started before the Mocha task completes. This ends up skewing the reporting output from the tests. Whereas, using Grunt, the Karma task doesn't start until the Mocha task is complete.

@codydaig It looks like the Gulp test task is running both the Karma & Mocha tests in parallel.. The task defined here https://github.com/meanjs/mean/blob/master/gulpfile.js#L222, can be updated to this

// Run the project tests
gulp.task('test', function (done) {
  runSequence('env:test', 'mocha', 'karma', done);
});

This will run the Mocha task first, and then run the Karma task. Learned something new about run-sequence :) anything that you want to run in parallel, you just group them within an array param of runSequence() But in this case, I think we want Mocha to run first; to be consistent between Grunt & Gulp.

@mleanos I'm working on refactoring the gulp file to be more inline with the grunt file. This was just a bug fix in the meantime. I'm happy to make the change if thats desired in this PR as well.

[mleanos]

@codydaig I think making that change in this PR is appropriate. Just so that this particular Gulp task outputs the results in a readable manner.

[codydaig]

@mleanos Change has been made.

[mleanos]

Perfect. LGTM. Thanks @codydaig

@rhutchison Any comments on this PR? I think you we're one of the guys pushing for gulp.

@codydaig regarding what were you looking for feedback from @rhutchison?

[codydaig]

@ilanbiala I'm pretty sure it was @rhutchison that was pushing for the gulp change, and had made some improvements in the gulp file in the past. But I've tested this and it makes it so you can run the tests with gulp, so since ryan doesn't have any feedback, then I think it's good to merge.
