'mazer list' on multi-content repos looks for install_info in the wrong places

Bug Report

After installing a multi-content repo that includes multiple roles (like git+https://github.com/theforeman/forklift from #112), then running mazer list, the list output will fail to find role/*/meta/main.yml and role/*/meta/.galaxy_install_info for most repos.

The meta/.galaxy_install_info is created on install, but the list command ends up looking in the wrong dirs for the role meta/main.yml.

The list command will find the repos and contents, but wont show version info.

Checking debug logs shows

[2018-08-08 12:25:04,283 12263 D] ansible_galaxy.role_metadata load_from_filename:49  - looking for content meta data from path: /home/adrian/.ansible/content/forklift/disable_ipv6/roles/disable_ipv6/meta/main.yml

/home/adrian/.ansible/content/forklift/disable_ipv6/roles/disable_ipv6/meta/main.yml is incorrect, and should be /home/adrian/.ansible/content/forklift/forklift/roles/disable_ipv6/meta/main.yml

The content name is being used instead of the repo name when finding the metadata/install info
