get function does not give ACL errors

doing a `gr.get(sys_id)` does not show any errors when we have a RoleException

doing it via `gr.query()` however does -- need this to be more consistent

e.g.

```
        test = self.client.GlideRecord('sys_atf_test')
        test.add_query('sys_id', sys_id)
        test.query()
```
vs
```
        test = self.client.GlideRecord('sys_atf_test')
        test.get(sys_id)
```
