Comment (by paulschreiber):

 How about this to clean up the list?

 {{{#!php
 <?php
 $allowed_extensions = array_filter(
     array_map(
         function( $item ) {
             return preg_replace( '/[^A-Z0-9]/i', '', $item );
         },
         $allowed_extensions
     )
 );

 if ( ! $allowed_extensions ) {
     return new WP_Error( 'image_sideload_failed', __( 'Invalid extension
 list.' ) );
 }
 }}}
