Add hasWrapper function in clean and remove command

[voxsim]

@arcanis sorry I totally forgot to inform you that clean and remove command miss a hasWrapper function.
This should fix both commands after #3105

Let mw know,
cheers,
Simon

Oh, thanks. Curious Travis didn't catch that.

@arcanis the main problem is that every command has tests that use directly the run function; instead this problem is in src/cli/index.js; they are kinda like integration tests. We can think to add a test for every command in __tests__/index.js as acceptance test that covers the whole path; What do you think? I think we didn't do that before to have fastest tests :P
