Describe the Bug

After updating to Next 12.0.2 (from 11.1.2) I can no longer have the imgix loader configured in next.config.js with the path as an empty string.

Error message that I get

Error: Specified images.loader property (imgix) also requires images.path property to be assigned to a URL prefix.
See more info here: https://nextjs.org/docs/api-reference/next/image#loader-configuration

The reason I need this is because I load my images from Prismic, which uses imgix behind the scenes, so it's the same imgix API, I just don't have direct access to the filenames because they are dynamically loaded from a CMS.

We load our images using their API so an example of our image component is
<Image src={prismicData.image.url} alt={prismicData.image.alt} />

This means we can't use a path prefix because it will append the path in front of the prismic response that we get.

Prismic also returns us different URLs based on if it's a PNG or an SVG. Meaning we get SVGs from my-website.cdn.prismic.io while we get PNGs from images.prismic.io but there is no difference in the API response apart from the URL for these types.

Expected Behavior

Allow me to continue using the images: {loader: "imgix", path: ""}

To Reproduce

Create a next.config.js with {images: {loader: "imgix", path: ""}}
