Correct check on SQLiteRawStatement.getColumnName

The function sqlite3_column_name() can be called on any prepared
statement; it is not a function of the data row that may have been
retrieved.  Therefore, the bounds check for getColumnName() should use
sqlite3_column_count() and not sqlite3_data_count() (which requires a
row of data in the prepared statement).

Two test cases have been added.
