Source/JavaScriptCore:

* inspector/agents/InspectorDebuggerAgent.cpp:
(Inspector::InspectorDebuggerAgent::cancelPauseOnNextStatement):
Clear this DebuggerAgent state when we resume.

LayoutTests:

* inspector/worker/debugger-pause.html:
Make this test work for WebKit1 where the VM is shared between the
page and inspector page. We need to be able to stop the Inspector's
evaluation, so that we can evaluate and pause on the page, and then
come back to the inspector afterwards.
