More PHP warning

Hello,

The same issue reported here: https://wordpress.org/support/topic/2-php-errors-on-latest-version/
is also present on line 453 of class Media_Library_Organizer_Common (in /includes/global/class-media-library-organizer-common.php)

Searching through the code for wp_get_current_user()->roles[0] (which is the problematic code) shows a few other instances, and I’d recommend searching for, finding, and fixing those as well.
