Fix modified schema deploy error

[Br3nda]

Travis isn't deploying to staging - instead, it has an error about the schema file changing.

The error Travis-CI during deploy is:

Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git checkout -- <file>..." to discard changes in working directory)
	modified:   db/schema.rb

I've re-run migrate, and the schema version format has changed in Rails 5.2. Here's the modified file needed.

I merged this, so we can fix staging deploys. It seems trivial enough
