Don't raise when we can't find a Gemfile (#48)

* Handle the case where we can't find a Gemfile without raising

This fixes tests in query_packwerk when run without bundle exec.
Usually this sort of thing is not an issue, so fixing it here prevents
it from causing problem unnecessarily.

* Bump patchlevel to 0.26.1 for bundler fix

* Update lib/parse_packwerk/configuration.rb
