Fix display of local file links

The code that shows an IRI for URLs if no display-string is provided
used to display with double slashes when it happened upon a simple
local filename link, like this:

=> /some/file.gmi

Result:

→ ///some/file.gmi

In order to fix this, we need to make sure that url-fullness remains
nil. This commit makes sure that it is only set if the URL in question
does in fact have a non-empty host (an empty host results in a host of
"" is a true value, so we need an extra test using string-empty-p).

This happens in both elpher-address-from-url and
elpher-address-from-gemini-url.
