Review note: The changes are complete, because self.options.descriptors
is set to None in parse_args (test_framework.py).
A value of None implies -disablewallet, see the previous commit.
So if a call to add_wallet_options is missing, it will lead to a test
failure when the wallet is compiled in.
Add an explicit sync_blocks call in wallet_orphanedreward.py, which was
missing and could lead to intermittent failures of the test due to
race conditions.
This will presumably fix https://github.com/bitcoin/bitcoin/issues/22181.
