Can't open fresh folders with `.link` files

[kirillt]

By "fresh" I mean folders without .ark subfolder. This means there is any link lacks metadata and preview. Half-initialized folders must be openable, too. In other words, user should be able to copy-paste file externally into the folder and we should catch up with all missing data.

What we do in case a link lacks metadata:

• If the link is not mentioned in user/properties, we query OGP and record all required fields into cache/metadata
• If the link also lacks data in user/properties, then we query OGP for missing fields and put them into cache/metadata
• If the link has all necessary fields in user/properties, then we don't query OGP

What we do in case a link lacks preview:

• We just download it and put into cache/previews

@kirillt can you give me the logic for this bug?

@Rizary oh, I forgot that we already have this issue registered here. I think, we've discussed it during the call. The idea is that .link files can come externally, i.e. if the user just copies them in a file browser, or saves from a messenger, etc.

In this case, first launch should request all metadata, put it into cache/metadata storage and use as fallback for properties. The user is free to override the title/description and such values should be stored in user/properties. We need spinning circles to demonstrate that there are internet requests running in background about particular links. We also need to make title optional.

May be related to this issue but I created my links using Shelf itself. And they fail to open when I want to browse them
