This fixes a regression introduced in #8242. Before this PR, the commands were always getting the current container registered in the kernel. But as the commands are now registered only once, if the container changes, the commands were not aware of this change. That happens quite frequently in functional tests where the Kernel is booted and shutdown several times in the same process.
