pack_commands key error for nodes without redirect

[ajh123]

So when pack_commands stumbles onto a node without a redirect key, for example the generated command graph from $ java -cp minectaftserver.jar net.minecraft.data.Main --reports, python generates a KeyError so it should be warped in a try/except for key errors, and if there is one pass.

I dont know how to fix, but also they should fix a bug when unpacking commands from paper, It fails on their special commands, I was trying to add my own with a proxy, but It failed.
