Part6b: Part 6.9 exercise doesn't reset step numbering

[marcindulak]

It would be expected that after the change of the title from anecdotes in 6.8: anecdotes, step6 to Better anecdotes in 6.9 Better anecdotes, step7, the step numbering is reset to 6.9 Better anecdotes, step1.

I think it would be better to remove better, and continue the numeration because its same project

Thank you for the issue. In part 6, there will be developed one and same anecdote application through the part. I renamed the exercises so it should be clear now.
