Infinite loop in PrivilegeHelper.isWheelOrRoot() for wheel user

def gs = GrouperSession.start(SubjectFinder.findByIdentifierAndSource("my-uid", "pid", true))

Stem s = new StemSave(gs).assignName("unc:app:temp:base:hr:org").assignCreateParentStemsIfNotExist(true).save()

It takes a few minutes to create this group from a remote vpn connection. With a debugger, it is doing an uncached group lookup on etc:sysadmingroup 1000's of times. And specifically for adding a stem, there are also many calls to retrieve an uncached etc:objectTypes:grouperObjectTypeMarker attributeDefName.

Some preliminary tracing shows that PrivilegeHelper.isWheelOrRoot() is calling GroupFinder.findByName() for etc:sysadmingroup, which is itself calling PrivilegeHelper.isWheelOrRoot().

We were previously on 2.4 patch 86 and didn't have this performance issue.
