[Bug] On a fresh install with no feeds copy/open link panics

[NickLarsenNZ]

russ/src/app.rs

Lines 546 to 547 in abb911c

	let feed = self.current_feed.clone().unwrap();
	feed.link.clone().unwrap_or_else(|| feed.feed_link.unwrap())

I could update it to look like the piece a few lines down, like:

                if let Some(feed) = self.current_feed.clone() {
                    feed.link.clone().unwrap_or_else(|| feed.feed_link.unwrap())
                } else {
                    "".to_string()
                }

But I think it might be best to instead change the signature to

fn get_current_link(&self) -> Option<String> {
// ...

Then update the pieces of code that call it, do do nothing if it is a None variant.

Or perhaps add a variant to Selected to represent when nothing is selected, which is the case on a fresh install.

russ/src/modes.rs

Lines 2 to 6 in ed7757e

	pub enum Selected {
	Feeds,
	Entries,
	Entry(crate::rss::EntryMeta),
	}
