Different return of `filepath` & `cwd` when using electron-packager to package an App

[hzlzh]

We are using gulp-usemin in our WeFlow at tree 1.4.0 just found that wrong values returned after packaged(using electron-packager) it into an App, here is some more details:

Before packaging (Under developing)
All the paths are correct as we hope and the App goes well.

After packaged (Released as app)
Both of filepath and cwd values are wrong and case the App down.

BTW, we'd met nearly the same kind of problem with another repo: gulp-rev-all#issue-152 here, you may read for the reference.
Since that repo's author did not show up for a long time, we can only fix it and push it as a new fork repo here: weflow-rev-all 😢

Any idea with this problem?

If any other information is needed, just let me know :)
