0.4.81 smart filter: can't target a node in the middle of a chain

Hey there,

Taking this example from the docs/: https://paste.sr.ht/~stacyharper/d909ebb4ff9c44998b59a0d0b408135e6ae1ab9c

We should be able to pw-play --target loopback-2-sink ....

If I understand correct, get-filter-from-target.lua currently override this and re-target input.loopback-1-sink.

This is an easy to reproduce example, but in my personal situation, I'd like to use one loopback node to merge different streams using a similar pw-play --target command.

Thanks!
