CueSettingAlign.UppercaseKeyword assertions incorrect

```C++
 /**
   * We're expecting a WEBVTT_INVALID_CUESETTING error on the 25th column of the
   * 3rd line
   */
  ASSERT_EQ( WEBVTT_MISSING_CUESETTING_DELIMITER, err.error() );
  ASSERT_EQ( 3, err.line() );
  ASSERT_EQ( 30, err.column() );
```
That comment reflects the nature of the test, however the assertions do not. So I'm getting this had been some hack to get the test to pass. Those assertions are quite wrong though, they should match the comment.
