[chromium] some inspector tests are flaky on linux/windows (they're all skipped on mac)

[Ojan Vafai]

WIN LINUX : http/tests/inspector/extensions-ignore-cache.html = PASS TIMEOUT
WIN LINUX : inspector/timeline/timeline-network-received-data.html = PASS TEXT
WIN LINUX : inspector/debugger/live-edit.html = PASS TEXT TIMEOUT

I was looking at live-edit.html for another reason. I noticed that the test failed right off sometimes because 
    var panel = WebInspector.panels.scripts; 
was undefined.

In Bug 97272 I added a call to 
    WebInspector.showPanel("scripts");
so maybe this case is not so flaky now?

Chromium and V8 have left the building. Won't fix.
