fix: NostrTransport.update_relays() KeyError

Browse Source 
`NostrTransport.update_relays()` raises a `KeyError` when the offer of
the configured swapserver (`config.SWAPSERVER_NPUB`) is not in
`self._offers` even though `sm.pairs_updated` gets triggered. This
happens because `NostrTransport.get_pairs()` called `sm.update_pairs()`
before adding the received offer to `self._offers`.
