fix(plugin-ris) fix parse function

Closes #66

I tried to run yarn test of this project, but in fails big time... I think this could be related with this being a multirepo and all that stuff. Any insight (just because I'm curious) about this?
I even used nvm use v6, for using the proper version of node this project states it supports, just in case it was because of my node version.

IDK what I have to do to improve the coverage here, if anything.
I understand that it's related to tests and that codecov (first time dealing with it) isn't happy because there is a decrease of coverage percentage, but I checked the tests for plugin-ris and I don't get them, how to improve the coverage... plus what I commented previously about tests doesn't even run OK in my machine, but dependencies problems. In this project there are several package.json and it seems that only installing dependencies of the plugin-ris package.json is not enought, neither also installing dependencies of citation-js, so I'm clueless, right now >_<.

Thank you!

To run the tests, you probably need to run npx lerna bootstrap. That installs (and links) the dependencies of the individual packages, while npm install, in this repository anyway, only installs generic devDependencies. After, yarn test and npm test should work. It's all in the new CONTRIBUTING.md, but the one in the v0.5 branch, not the one in master. That's my bad, sorry for the confusion.

Either way, you don't have to worry about the code coverage.

Hi, @larsgw. One question: why is it needed to trim() line here when line already comes trimmed from line 52?

[larsgw]

The second one can be removed, the line needs to be trimmed for LINE_MATCH mainly. That second one comes from eba2bfe which hasn't landed on master yet.
