Test suite failure for package ghc-exactprint-0.6.2

[juhp]

In the Stackage Nightly Nightly build:

    GHC88
### Error in:   5:Default Annotations round-trip tests:1:ghc80:150:SemicolonIf.hs
    ExitFailure 1
Cases: 1979  Tried: 1979  Errors: 1  Failures: 0
    Counts {cases = 1979, tried = 1979, errors = 1, failures = 0}

This is still an issue today.

At least tests are running locally for ghc-exactprint-1.7.0.1 on ghc-9.6 - so I've re-enabled the tests on stackage nightly.
