Fixed bug creating duplicate subscribers through the REST API

A customer reported that they were seeing duplicate subscriber records being created through the REST API.

After some debugging, we found that posting the same email address with mixed-case letters, for example, bob@example.com and Bob@example.com, bypassed the duplication check.

We have now put a fix in place to prevent this from happening, along with additional tests to ensure it doesn't break again in the future.
