patch 9.1.0259: Normal mode TextChanged isn't tested properly

Commit: https://github.com/vim/vim/commit/c422662933275484e61af79d8148898337a5c38e

    patch 9.1.0259: Normal mode TextChanged isn't tested properly

    Problem:  Normal mode TextChanged isn't tested properly.
    Solution: Combine Test_Changed_ChangedI() and Test_Changed_ChangedI_2()
              and also run it on Windows. Fix a typo in main.c.
              (zeertzjq)
