Ghost v3, custom favicon.

[VDShark]

Hello.

It looks like the custom publication icon doesn't work properly when using ghost-digitalocean storage adapter. I didn't dive too deep, but probably the problem in the storage.

Steps to reproduce:

1. upload publication icon;
2. open the page;

The thing is - they used /favicon.png (or ico, depends from the extension) as URL for resolving the correct icon. And at this address, we got 500 error ("is not stored in digital ocean").

Error:  is not stored in digital ocean

Not sure, on which side is the problem. They called the storage read method here https://github.com/TryGhost/Ghost/blob/6b420d0cbd2ae6e85b1c46bb07849049da8a9223/core/server/web/shared/middlewares/serve-favicon.js#L53
