Related to PR 73 in sdntrace_cp

Summary

Update tests related to the changes in sdntrace_cp to add the loop and incomplete types.

Note that in all the failed traces there is now one more item with the type incomplete.

• When before it was []. now it is a list that contains one item with type incomplete.
• When before it was an array with x items, now it is an array containing x+1 items, and the type of the last one is incomplete.

@viniarck, I did what you suggested. Also, I added a new e2e test related to PR 76 in sdntrace_cp. Basically, I check that the example in the PR has the desired behavior once the flows are sorted by priority in /traces.
