Don't Latch on NotActive activation

The special NotActive activation placeholder appears to be triggering a Latch:

Similarly:

In the OnDelay case, this may be because state is ActiveLatched. We need to guard against OnDelay as well if NotActive, and perhaps also when Latched. This gets confusing as you start to mix and match overrides: JeffersonLab/jaws#24

Effective processor does not appear to latch on NoActivation. More investigation needed. Perhaps on startup some channels take too long to connect to EPICS and result in ChannelErrors, which eventually resolve to NotActive. In this case the issue might be the audit logger is capturing the wrong state: expected would be type ChannelError, not type NotActive.
