Release a version where `cabal test` succeeds

Almost a year ago I fixed `cabal test`:
- #273

@deech: Can we get a release of `c2hs` with #273 and the other latest fixes?

I would be good to have `cabal test` working. Then, e.g., tests could be switched on again in stackage: https://github.com/commercialhaskell/stackage/blob/358abb4150175b39d6fd818172cf8066051fea8d/build-constraints.yaml#L8581
Personally, I was confused to see `c2hs` tests failing and got worried that I caused these by my recent release of `shelly-1.11`.
