Pipe was broken in the previous rubucop fix

[asasfu]

Pipe was being set previously, 2 commits back, but then not used so rubucop complained. 1 commit back, pipe was then changed to being compared, which broke it because it was never set. This fixes that to remove the variable pipe altogether since we only use @resource[:pipe] once and don't need a variable for it. Brings it in line with things like @resource[:source]

Fixes #242

@asasfu Thanks for spotting my slip up. I suspected I'd probably messed up somewhere during the rubocop fixes, but couldn't seem to reproduce #242 when I tried this morning.

I hope to be able to add some acceptance tests soon.

You're welcome, I just only realized that this module has finally been resurrected in commits and you guys are doing a bunch of great work getting a lot more patched in. I've still yet to learn how to write tests, so i'll bow out of that task ;)

@asasfu The last rubocop fixes are in #241 Would you mind taking a look?

There are 2 types of test that could be added. We could add unit tests for the providers, or acceptance tests using docker. I'm looking forward to see what happens with voxpupuli/modulesync_config#230

@alexjfisher I Think #241 looks good. I was fairly thorough on my checking, but i'm not a professional programmer either :)
