User permissions aren't evaluated if group violations are disabled

[yuvalavra]

Because of a bug here -

rbac-police/pkg/eval/eval.go

Lines 302 to 306 in 1ec5d02

	if !evalConfig.UserViolations {
	collectResult.Users = []collect.NamedEntry{}
	}
	if !evalConfig.GroupViolations {
	collectResult.Users = []collect.NamedEntry{}

, disabling group violations would inadvertently cause user violations to be skipped as well.

So while ./rbac-police eval lib --violations users,groups and ./rbac-police eval lib --violations all worked as expected,
./rbac-police** eval lib --violations users wouldn't evaluate users.
