Remove `prefer_gems_rb` settinginit_gems_rb

In my opinion, it's overkill to provide a setting for how little this
setting was doing. Both types of Gemfile are supported and work
regardless of this setting. The only difference this setting would make
is the warning message one would get when having _both_ types of
Gemfiles in the same project.

I changed things so that gems.rb is always looked up first, and the
warning message in case you have both always tells you to remove Gemfile
and Gemfile.lock.
