Computer groups are reported as "unused" even if they are used for Restricted Software

[homebysix]

If a computer group is used in Restricted Software (either as a target or as an exclusion), Spruce doesn't omit it from the Unused section of its computer groups report.

Here's the relevant section of the Restricted Software API result:
