Following discussion in #123 (comment) this is the MR to improve path detection resilience by falling back to
which
whenbundle exec which
is failing (which happens with some bundler version).I've added specs for all the cases I thought about and improved a bit the current specs which where dependent on using bundler to run rspec, now they mock bundler presence so the result is reliable whether we start rspec with bundler or not.
Feel free if you have any questions. I'm thinking there's most probably a more standard / reliable way to get the path of a binary using Bundler methods instead of shelling out, but I'd rather not risk more changes here.
