587a66da47 Add a bunch of missing conversions for `Witness` (Martin Habovstiak)
Pull request description:
This is supposed to go in front of #4250
`Witness` lacked a bunch of APIs that were making it harder to use and test, so this also adds them in addition to cleaning up tests. (I only realized they are missing when I tried to clean up tests and got a bunch of errors.)
