Bug Fix: Cannot submit app when interconnecting Utility Changed Between Part I and II (from ComEd) 

Issue: When a Part I project application was originally submitted with the Interconnecting Utility specified as ComEd, but the Interconnecting Utility was later updated/corrected to a different utility company during Part I Verification, submission of the Part II application was being blocked by a validation error requesting to have a Net Metering Letter uploaded in the documents section. This document requirement is unique/specific to projects where the Interconnecting Utility is ComEd and should not apply to these projects.  

Fix: Part II Submission logic has been updated to account for this scenario.
