Jun Pataleta 2791334251 MDL-29317 gradeimport_csv: Case-insensitive query for email and username
Query using the following fields for
\gradeimport_csv_load_data::check_user_exists() should be done in a
case-insensitive manner:
* email - As agreed in MDL-29315
* username - Although usernames can only be in lowercase during
  registration, usernames are being handled in a case-insensitive
  fashion when logging in. It makes sense to make check_user_exists()
  consistent with this behaviour.
