Pull Request event is reporting user name instead of GH user account name

[jdmedlock]

Steps to Recreate:
Pull events for a repo and then examine the results returned from the get() function.

      const result = await gitAClue.get([
        {
          context: 'repo',
          contextOwner: 'jdmedlock',
          contextName: 'GitAClue',
          segments: ['events'],
        },
      ]);
