Product image builder - Override attributes when builder used multiple times

[ihor-sviziev]

Description

Image builder is used few times with different parameters in \Magento\Catalog\Block\Product\AbstractProduct::getImage.
In case when on first call $attributes was set to not empty array, on second call - $attributes is empty array - builder re-used attributes from first call, as result - we will get unexpected result - attributes will be re-used from 1st call.

$this->imageBuilder->setProduct($product)
    ->setImageId($imageId)
    ->setAttributes($attributes)
    ->create();

As builder designed to be used multiple times - let's remove check that attributes array is not empty.
