* Preserve command node when re-registering modern commands through old API
* make fix more targeted
mainly because it didn't work for vanilla commands :)
The brigadier command dispatcher is not capable of executing commands
that redirect more than one.
The exemplary alias 'minecraft:tp' may hence not redirect to 'tp' it
instead has to redirect to 'teleport' as 'tp' itself is merely a
redirect.
Prevent infinite recursion when declaring a cyclic relation between
command nodes via child nodes redirecting to an nth parent by marking a
command node as unwrapped before unwrapping its children.
Adds the ability for plugins to register their own brigadier commands
