Description

A product without an image using the img_url filter:
{{ product | img_url }}

Outputs a valid image URL:
//cdn.shopify.com/shopifycloud/shopify/assets/no-image-100-c91dd4bdb56513f2cbf4fc15436ca35e9d4ecd014546c8d421b1aece861dfecf_small.gif

A product without an image using the image_url filter:
{{ product | image_url }}

Outputs the follow error:
[Liquid error (snippets/image line 8): invalid url input](http://127.0.0.1:9292/products/test) [test](http://127.0.0.1:9292/products/test)

Nobody wants to see an error with a line reference to the store's source code on a production store due to a bad image link. I can't think of any scenario where this behaviour would be preferable.
This also breaks any proceeding image_tag filter.
Is this a bug?

Research direction

Start at the implementations and tests for the img_url and image_url filters, then reproduce both cases with a product that has no image. Done means image_url no longer emits invalid-url or source-line errors and remains compatible with image_tag, with regression coverage matching img_url.
