Use outputhash in regtests.

This updates the regtests to use "outputhash" for listunspent results
in some places, to make sure the code will also work after activating
segwit-light.

Some other places remain where outputs are not from listunspent and that
still needs to be updated when segwit-light gets activated generally,
but this is a first step to reduce the amount of required changes then.
