pasting openpgp4fpr:... links in the search don't offer to start chat

[adbenitez]

when you paste an i.delta.chat link it works but for openpgp4fpr: links (the actual original invite links) it doesn't work

So I think we need to run this fetch always and not only when we see an invite link:

deltachat-desktop/packages/frontend/src/components/helpers/PseudoListItem.tsx

Lines 145 to 148 in 0b9bb81

	const parsedQrFetch = useRpcFetch(BackendRemote.rpc.checkQr, [
	accountId,
	inviteLink,
	])

At least run it throttled or even debounced. Not super good for performance, but I mean we're anyways also doing RPC calls to search for messages and contacts.
Throttle period can be big, because nobody really "types" links: they just paste it once.
An alternative is to only run the fetch when we get 0 search results otherwise, but this might be bug-prone, e.g. you could have the link in your saved messages as a text, which would result in 1 message search result.

We'll also need to hide the result if the "QR" is a "text" QR. Maybe there are other such cases that need to be skipped.
