965899 - do not include component view label in composite view path

Prior to this change, when a composite view is promoted
(e.g. Library to dev), the content path on pulp file
system would include both name of the composite view
as well as the name of the component view.  The component
view name is not necessary; therefore, it is being removed
from the path.

E.g.
Before:
/var/lib/pulp/published/https/repos/ACME_Corporation/dev/comp_view/zoo_view/custom/zoo_product/zoo_repo

After:
/var/lib/pulp/published/https/repos/ACME_Corporation/dev/comp_view/custom/zoo_product/zoo_repo
965899 - added test for clone_repo_path for component view

Added a test to validate that the repo path that is used
when cloning a component view does not include that view's
label.  Instead, when a client interfaces with the repo
the full path will include the composite view.
