Counts printed by gen_test_comments include duplicates

[Saurabh Mathur]

The values being printed by gen_test_comments are

-------------------------
command 1672
statement 80993
question 131219
-------------------------

However, the actual values are 1111, 80167 and, 131001 for commands, statements and questions respectively. The values stored in the variables like command_count include duplicate sentences.
While the tagged_comments dict takes care of duplicate values, the counts still contain duplicates.

Fixed in latest commit :)
