Your version of imagick is indeed too old. The reason for the changes
is that Imagick::flattenImages() which was used previously in the
generation of the PDF thumbnails was removed in 3.3.0:
https://pecl.php.net/package-info.php?package=imagick&version=3.3.0
The replacement for this is
$im->setImageBackgroundColor('white');
$im->setImageAlphaChannel(Imagick::ALPHACHANNEL_REMOVE);
$im->mergeImageLayers(Imagick::LAYERMETHOD_FLATTEN);
so this pulls in the requirement for this constant, which was added in
3.2.0b2:
https://pecl.php.net/package-info.php?package=imagick&version=3.2.0b2
Note that 3.3.0 was released more than two years ago and 3.2.0b2 has
been available for almost five years already, released mere weeks
after 3.1.2 was released.
