get_unsigned_tx() assigned the computed locktime to a stray attribute on the PSBT, so the constructed transaction kept locktime 0.
get_unsigned_tx() asserted that every input has a sequence number, crashing on the minimal BIP 370 test vector.
The witness-detecting deserializer accepted witness-serialized unsigned transactions and misread valid ones with no inputs.
A provided unsigned tx with no inputs and outputs is indistinguishable from the empty placeholder.
The global PSBTv2 fields were already rejected.
compute_lock_time() was previously untested.
The test data now covers every vector from both BIPs; these all already pass.

Based on:
Each fix / hardening commit introduces the test vectors that cover it.
Mostly straight-forward, but
psbt: parse the global unsigned tx without witness datais worth a closer look. IIUC it catches up with bitcoin/bips#1099.
