Problem with gulp.watch, mocha and promisify

[c301]

When I using gulp.wach to run tests (mocha) on each changes of the files, nodegit initialized without error only first time. I've created repo to reproduce this problem (see README for error stack).

I ran into this issue earlier today, and found gulp-spawn-mocha to be a quick fix.
