mod_auth_internal_plain: Fix user creation done via mod_admin_shell Following the new behavior in auth_internal_hashed (c8f59ce7d3cf), the account will be created and disabled, instead of returning an error telling password being nil when calling saslprep(). Note that mod_auth_internal_plain does not have full support for enabled/disabled accounts, but that may be fixed in subsequent commits.
