Fix building testroms project

fixes b8d5dd899
also addressed code style warnings and fixed a typo in GambatteSuite.BeforeAll
note the last acid suite fail is gone after a recent SameBoy update,
unfortunately the same update added a bunch of fails in the mealybug suite,
though the suite itself needs updating too

 To build and run the tests in `Release` configuration (or `Debug` if you need that for some reason):
 - On Linux, run `run_tests_release.sh` or `run_tests_debug.sh`.
 - On Windows, pass `-c Release` to `dotnet test` (must `cd` to this project). Omitting `-c` will use `Debug`.
