fix(label): allow to use spaces inside the labels (#199)

* chore(git): ignore .idea folder to avoid adding WebStorm files

* test(jest): find all spec files as well

* refactor(labels): create a dedicated function to parse the labels

at first I thought that the parseCommaSeparatedString method was causing the issue so I move it to a dedicated file to test it since it was private
also because I think that this repo could have more clean code and code splitting
anyway this was not the root of the #98 issue :/

* fix(label): allow to use spaces inside the labels

* docs(isLabeled): add JSDoc

* chore(npm): add lint:fix script
