Auto merge of #5680 - bundler:seg-git-force-no-git-ops, r=segiddins

Allow bundle install --force to work with git specs

This allows `bundle install --force` to work when the gemfile includes a git spec, previously it would error nonsensically. This happened because sources needed to be `remote!`ed for installation to succeed, and this wouldn't happen when `--force` was called with no other changes to the gemfile.

Closes #5678

(cherry picked from commit 7f1411cdb3279c25e8e8f2a8e3c1f8acf3dbe8f2)
