> The PBHelper#convert(NamespaceInfoProto) function doesn't pass the build version from
the NamespaceInfoProto to the created NamespaceInfo object. Instead, the NamespaceInfo constructor
gets the build version using the static function Storage#getBuildVersion. DNs also use this
static function to determine their own build version. This means that the check the DN does
to compare its own build version to that of the NN always passes, regardless of what build
version exists on the NN.
