base: 'port uninstall' ignores subport when using 'current'

[Bradley Giesbrecht]

Is this intended?

$ cd $(port dir qt4-mac-mysql55-plugin)
$ for mysql in mysql5 mysql51 mysql55 mariadb percona ; do sudo port -dy uninstall subport=qt4-mac-${mysql}-plugin 2>/dev/null ; done
qt4-mac-mysql55-plugin is already uninstalled
qt4-mac-mysql55-plugin is already uninstalled
qt4-mac-mysql55-plugin is already uninstalled
qt4-mac-mysql55-plugin is already uninstalled
qt4-mac-mysql55-plugin is already uninstalled
$
