This reverts commit ec0c2426aa5fa6cee2efabd3ee6f175b41c35f64, reversing changes made to 26d750d09c84734f56c2dc18cb332a232e24fb6d. This reverts the fixes to the pruning of BIP32 derivation paths when creating a PSBT, in preparation of reverting the merge of this feature altogether. This is because always creating PSBT with only the BIP32 derivations for a single path broke the Ledger support.
