NIFI-10449: Fix ScriptedLookupServices to reload after disabled and first validation after changes made

[mattyb149]

Summary

NIFI-10449 This PR fixes an issue where ScriptedLookupService controller services were not reloading at certain times, such as after being disabled with no changes made. This causes things like Parameter value changes not to be picked up. The approach to the fix was basically to do the same as is done with InvokeScriptedProcessor and other scripted controller services.
