Subject: [PATCH] remove default null value for asset version

Setting `null` as the version of a package means that it uses the empty
version strategy. However, omitting the `version` option entirely was
meant to fall back to the default version strategy. This is not possible
when the default version value is `null` as there is no way to remove
it.
