foreman_heal appears not to remove host membership to empty clouds

• QUADS version (quads-1.1.2-20200110.noarch)

If a host is still "owned" by a cloud in foreman (from a previous allocation) but that allocation has expired (i.e. empty), when you run foreman_heal you don't seem to remove the ROLES from the now empty cloud. For example:

• hostA belonged to cloud13
• schedules expire and move back to cloud01 but nothing was done to remove the host roles from cloud13
• Running foreman_heal appears to skip the removal of hosts from cloud13 user in foreman, because the quads allocation for cloud13 is empty.
