New app: resolved the display issue when test result in "Results" tag was expanded and overlapped with the top bar after switching between tags.
This could be shown as follows: (iPhone 5s, iOS 7):
1. Go to RESULTS, show item
2. Go to SUMMARY
3. Go back to RUN - you see the problem
- fixed by always restoring the view controller's table view when entering the tab.

New app: fixed layout issues in the Summary screen:
- no longer overdraw the central graph icon
- ensure that "Network Latency" can be displayed neatly
