[PATCH 2/3] fetch --prune: Always print header url

[Tom Miller <jackerran@gmail.com>]

If fetch --prune is run with no new refs to fetch, but it has refs
to prune. Then, the header url is not printed as it would if there were
new refs to fetch. the following is example output showing this
behavior:

$ git fetch --prune --dry-run origin
 x [deleted]         (none)     -> origin/world

After this patch the output of fetch --prune should look like this:

$ git fetch --prune --dry-run origin
From https://github.com/git/git
 x [deleted]         (none)     -> origin/test
