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.
At startup it sometimes appear we may be hanging when setting up
bitcoind. Add more loading to give more information about what's taking
long to setup (for instance, loading the watchonly wallet).
