FFS-2397-2: use remote_ip instead of ip

[millerti]

FFS-2397

Changes

In acceptance testing, we found that the user profile created did not ALWAYS match the location of the user creating the event. This is an experimental fix because I can't figure out how to test it locally... I need it to be running in demo so that request.ip and request.remote_ip resolve to something other than 127.0.0.1.

Acceptance testing

• No acceptance testing needed
  • This change will not affect the user experience (bugfix, dependency updates, etc.)
• Acceptance testing prior to merge
  • This change can be verified visually via screenshots attached below or by sending a link to a local development environment to the acceptance tester
  • Acceptance testing should be done by design for visual changes, product for behavior/logic changes, or both for changes that impact both.
• Acceptance testing after merge
  • This change is hard to test locally, so we'll test it in the demo environment (deployed automatically after merge.)
  • Make sure to notify the team once this PR is merged so we don't inadvertently deploy the unaccepted change to production. (e.g. :alert: Deploy block! @ffs-eng I just merged PR [#123] and will be doing acceptance testing in demo - please don't deploy until I'm finished!)
