semver-git gives proper version on dirty working tree

[deepy]

If we have a tagged version and a dirty working tree, semver-git gives us the tagged version.

The expected result is probably rather a SNAPSHOT.

This is because the dirty marker is only added if a there is a <dirty> placeholder in ext.snapshotSuffix, which by default is just SNAPSHOT.

I agree this is unexpected, though.
