Clean up duplicate account merge script

[JackHaeg]

Overview

The PR (#1612) needs to union any existing arrays instead of appending them. There are multiple .push uses to arrays that might result in containing duplicate information:

• skillsToMatch
• projects
• managedProjects
  Using a set will solve this problem.

Action Items

• Switch from using array .push to a set for:
  • skillsToMatch
  • projects
  • managedProjects
• Preserve the highest user access level
  • admin > user
• Implement script as python notebook so that changes can be made incrementally
• Submit PR
• Merge accepted PR into the feature branch: correct-db-casing

Resources/Instructions

• This issue is part of the epic: Epic: DB accepts capital and lower case email credentials for email login #1456

@dannyprikaz to work on updating this issue this week per tonight's All team discussion.

(I believe this is related to adapting this issue to a python notebook or making your own and closing this issue, but I could be wrong - we spoke about this in further detail on the call and you mentioned additional steps, so I realize this may be an outdated summary - sorry!)
