Medialibrary doesn't handles file conversion errors gracefully

[driesvints]

When, for example, a corrupt PDF is uploaded and a file conversion is defined to create a thumbnail, an Imagick error is thrown. This error bubbles up in the call and ends up with the user instead of it being gracefully handled and an error message is shown.

Example PDF: drupal-and-vuejs.pdf

Example code:

$this->addMediaCollection('slides')
    ->singleFile()
    ->registerMediaConversions(function (Media $media) {
        $this->addMediaConversion('preview')
            ->width(368)
            ->height(232);
    });

I personally think Medialibrary (Pro) can do better here, catch all similar errors and display a descriptive error message in its components telling something went wrong and suggesting to review the file that was attempted to upload.
