Freshly uploaded file is presented as being shared by null in file details page

Expected behaviour

Share information should be hidden for self-owned files

Steps to reproduce

1. upload a file
2. go to file details
3. show shared tab
4. observe that file is shared by null

Environment data

Device model: OnePlus 6T
Stock or customized system: stock
Nextcloud app version: master
Nextcloud server version: 17

Additional info:

• ownerId is refreshed after pull-to-refresh

Share information is shown if accountOwnsFile evaluates to false.

    @Override
    public  boolean accountOwnsFile(OCFile file, Account account) {
        return !TextUtils.isEmpty(file.getOwnerId()) && account.name.split("@")[0].equals(file.getOwnerId());
    }

Immediately afetr uploading a file TextUtils.isEmpty(file.getOwnerId()) is true.

@tobiasKaminsky Would that work?

    @Override
    public  boolean userOwnsFile(OCFile file, User user) {
        return TextUtils.isEmpty(file.getOwnerId()) || user.getId().getUsername().equals(file.getOwnerId());
    }

Looks good to me, as when a new file is created, the current user is the owner 👍
