fix (gen:endpoint): Remove "s" after "<%= name %>" in endpoint templates

[covertgeek]

The endpoint generator adds an additional "s" to the controller and test spec files. This is to remove the additional "s" in the templates.

Thanks for pointing this out. Had to do a slightly different fix though.

@DaftMonk I believe this is issue in the name.controller.js file also. Do you agree?

[DaftMonk]

Not sure if theres something specific you're referring to, but the controller looks fine to me.

I was mistaken. In the index function (ln 9 & 11), I saw the pluralization of the model and made an assumption. It makes sense now and isn't actually an issue. Thanks for your patience with a newbie. :)
