Bug: Cannot login in Booth in branch ortosia-mixnet-auth

[prsaseta]

Description: When attempting to login in the booth view, the server returns an internal server error. This bug happens exclusively on ortosia-mixnet-auth and merged branches.

System info: Running Django outside of Docker in a local machine running Windows 10.

How to reproduce: Attempt to login normally in booth to vote.

Additional data: This is the error showing on console:

We request a fix to be investigated and deployed ASAP, since it completely blocks the normal usage of the application and prevents any testing done that includes voting.

After @alvarogonjim fixed the bug in ortosia-mixnet-auth, I merged into ortosia-mixnet-prepro to test, where the same bug (I don't know if the same source) appeared again.

Issue found and fixed at settings.py; the email backend specification was missing.
