fix(duser_db): Guard against NULL values
When a user is deleted, their details are set to NULL. When no username is specific for a password reset, this can trigger an email being sent to an empty recipient which will not be deliverable. Just to be safe, guard against NULL values for all the user related functions. Signed-off-by: Florian Pritz <bluewind@xinu.at>
