Issue with updating PR report after changing description

[bslabiak]

updatePR : description

Steps to reproduce:

1. Run test
2. Report has been posted into PR description
3. edit description
4. Run test again

Results:
Test report is not being updated on description and still display old report (without editing step it seems not to appear)

updatePR : comment

Behaviour is very similar but it is rare to edit a comment.
Next run of tests in same PR is updating same comment.

Is this possible to post new comment after each run to track history of test results properly?

At the moment, default behavior is to always edit comment/pr, so posting a new comment is not possible. I would need to double check why github api doesn't allow to edit comment anymore after it has been edited by someone (it can potentially be a limitation of GitHub).

I believe this should be fixed by #738
