refactor: use login_id to match canvas and openedx users

[tecoholic]

What are the relevant tickets?

Following up on #590

Description (What does it do?)

When matching the users between openedx and canvas, we use the "login_id" instead of the "email" in Canvas's response, as matching on email doesn't seem to be working in production.

Screenshots (if appropriate):

N/A

How can this be tested?

Following the testing instructions in #500

Additional Context

• We also add a log.debug statement to log the full Canvas response. We decided to do this for short-term debugging as we don't have any visibility into Canvas's logs.

Can you just bump the patch version as well so that the publishing goes out properly?
