Onceover tries to use bundle if a Gemfile is present in Control-repo.

[16c7x]

If a Gemfile is present in the root of a Control-repo and the --parallel flag is used, onceover will try to use Bundle to install the parallel gem even if Bundle is not installed.

Steps to reproduce:
docker pull puppet/puppet-dev-tools
docker run -it puppet/puppet-dev-tools /bin/bash
Clone in a control repo
Ensure a Gemfile is present in the root of the control repo
run onceover run spec --force --trace --parallel
You should see an error saying Bundle is not available.
Then remove the Gemfile
run onceover run spec --force --trace --parallel
Onceover will ignore the --parallel and continue to run the jobs in series.
