Problem/Motivation

While creating new multichoice question by user with no quiz_multichoice_user_settings I've faced this error:
Deprecated function: Automatic conversion of false to array is deprecated in MultichoiceQuestion->getDefaultAltSettings() (line 707
The reason is that in the 'elseif' branch $settings are set as FALSE by getUserSettings() and then in the 'else' branch attempt to convert it to array leads to warning in PHP8.1.

Proposed resolution

I suggest to return NULL instead of FALSE in case of query gives no result or fail.
