children interruptions are counted as parent session errors

[maormarcus]

in case there's interruption in child, it is counted and displayed as parent session errors

@vmalloc do you think we should count this cases as parent interruptions (in case the interruption is created from the parent it will be counted more than onec) or ignore them?

Good question. I think counting interruptions twice is not too bad. Any other drawbacks?
