Update db call to to receive email strings back from the db in lower case form

Dependency

Complete after #1551

Overview

This is part of #1456

We need to receive email addresses as lowercase from the db so that duplicates of different casing ([email protected], [email protected]) aren't able to be created.

Action Items

Either:

• Update the db so that all emails are already lowercase
  (this is the preferred solution, but we will need to handle duplicate addresses which increases complexity)

Or:

• Update the db email address call to receive back email addresses in lower case format

Resources

• MongoDB Docs

We're in luck here, the production DB only has two duplicate emails eg jeff@example, Jeff@example and ~40 emails that have upper case letters in them. Enough that a manual edit isn't a huge burden.

That means we don't need to update the DB call to return an email in lower case format. Win!

@spiteless There is a { lowercase: true } value that can be added at the db layer to avoid all these manipulations on the FE.
