    test: Remove workaround for SpiderMonkey GC code coverage
    
    There used to be a bug in SpiderMonkey where a GC would sometimes erase
    realm code coverage data. This bug no longer exists, so remove the
    workarounds that would skip tests when run under code coverage.
    (The bug was https://bugzilla.mozilla.org/show_bug.cgi?id=1447906)
