fix(Feed): extract shorts uploadDate from feedInfo

Shorts extracted from the Shorts tab do not have an uploadDate.
They are currently saved with their uploadDate set to -1. This results
in them to appear at the end of the feed. To fix this, we can use the
generic FeedInfo that contains the uploadDate. This also fixes an issue,
where old shorts were fetched on every refresh.
