remove user chapter, replace with user chapter role

[timmyichen]

• I have read Chapter's contributing guidelines.
• My pull request has a descriptive title (not a vague title like Update README.md).
• My pull request targets the master branch of Chapter.

This PR:

• Removes the UserChapter model
• Adds factories/seeds/etc for UserChapterRole model

Strangely enough, I can't seem to get a migration running for this. Any ideas?

tim@dropten:~/chapter$ npm run typeorm migration:generate -- --name=RemoveChapterUser
> chapter@0.0.1 typeorm /home/tim/chapter
> ts-node -P tsconfig.server.json -r tsconfig-paths/register node_modules/typeorm/cli.js "migration:generate" "--name=RemoveChapterUser"
No changes in database schema were found - cannot generate a migration. To create a new empty migration use "typeorm migration:create" command

I think I know that the problem is. TypeORM is really finicky when it comes to changes relations. So when you change the migration table it doesn't actually change the migration.

Try creating a new migration for a slightly different column eg users123, run the migrations, and then manually change stuff around in the migration file.

To summarize for myself, and for anybody else watching, it sounds like these changes are furthering the work of #335 and #345 and endeavoring to create a migration to make the schema changes which were previously only part of the models? Is that correct?

Regarding automatically updating the schema image, we have that in progress on #54 and #360 (comment)

Any progress with this @timmyichen?

Seems fine, just one small change
