Critical Bug: PlanId not updated to developerPlanId in invokeBlinkUp.

Symptom: Objective-C plugin actually sees collection instead of string.
Fix: passing in the correct plan id.
Tested:
- blinkup, clear blinkup. relaunch of the application after successful blinkup.
- launch application without developer plan id.
