Fix lasttag expression to get "latest tag *so far*"
Turns out that the old version has always shown the last tag available
instead of last tag available *so far*, i.e. up to the current HEAD.
This made it impossible to determine version correctly when an older
version was checked out, i.e. installing or packaging an older version
would result in broken versioning.
