Method getUrl in Magento\Catalog\Model\Product\Attribute\Frontend returns image url with double slash

[igortregub]

Preconditions

1. Magento 2.2.2

Steps to reproduce

1. Try to get product image via method getUrl from class Magento\Catalog\Model\Product\Attribute\Frontend

Expected result

1. returns image url without double slash

Actual result

1. will be returned image with double slash
   

I think it happens because images have in method getUrl variable $image image path starts from slash.
I here is sample how issue could be fixed: #13498
