GroupAnyAttributeFilter() matches partial group names as well as attribute values

groovy:000> def x = new GroupAnyAttributeFilter("sysadmingroup", StemFinder.findRootStem(gs)).getResults(gs)

===> [Group[name=etc:sysadmingroup,uuid=b486380c757446ef86644ec690792465]]

It looks like this was introduced in 1.5.0. it's not just matching on the group name, but the display name too.

move group 1 to 1 attributes to group table

Can this be changed to just query attributes and not the group names? If I want to act on the resulting set of groups and do something with the attribute, I don't want to get groups that don't actually have the attribute.
