Filter out the Test Cases from the issues in the TriageBot

Currently, the TriageBot includes the Test Cases into the issues that are handled. If I try to catch all issues that does not have a weight, they are all found and modified (in vain). If I try to identify all the issues that doesn't have an Epic related, they are found and modified (in vain again).

Test cases cannot have an Epic or a Weight, so you find them each and every time. Everything is fine, until you get enough Test Case to receive the Too_many_request error in the triage bot.

I couldn't find any field that tells us if the current issue is a Test Case or a 'real' issue. Is there something/field that I missed (seriously hope so!).
