[BUG] `PotFactory.whitelisted_deployers` is incorrect in prod/dev

[lachlanglen]

Describe the bug

When I call get_config() on the potfactory contract, I get the following response:

View call: v1.potfactory.potlock.near.get_config()
{
  owner: 'potlock.near',
  admins: [ 'plugrel.near', 'impact.sputnik-dao.near' ],
  protocol_fee_basis_points: 200,
  protocol_fee_recipient_account: 'impact.sputnik-dao.near',
  whitelisted_deployers: [
    'lachlan.near',        'plugrel.near',
    'wendersonpires.near', 'builddao.near',
    'james.near',          'efiz.near',
    'ossround.near',       'airound.near',
    'buildersround.near',  'africaround.near',
    'ecofund.near',        'ukraineround.near',
    'collegeround.near',   'ndcround.near',
    'marketinground.near', 'marketingdao.near',
    'carina.akaia.near'
  ],
  require_whitelist: true
}

However, when I view the PotFactory in the django admin dashboard, there are no whitelisted deployers:

This is confirmed in the django shell on dev:

We need to:

• Determine why whitelisted_deployers is not up to date (review indexing logic, including for this recent transaction which should have been indexed)
• Fix indexing logic & reindex so that correct whitelisted deployers are saved in db
