target doesn't work as intended

	```yaml
	fixtures:
	repositories:
	firewall: "https://github.com/puppetlabs/puppetlabs-firewall.git"
	stdlib: "https://github.com/puppetlabs/puppetlabs-stdlib.git"
	control_repo:
	repo: "https://github.com/puppetlabs/control-repo"
	target: "spec/fixtures/control_repos"
	```

results in spec/fixtures/control_repos/control_repo clone instead of control_repo module being cloned into spec/fixtures/control_repos

So similarly if you had something like puppet_agent7 with target of spec/fixtures/modules/puppet_agent it would result in spec/fixtures/modules/puppet_agent/puppet_agent7 being the directly clone.
