IndexedDB: Remove m_contextStopped from ActiveDOMObjecs

IndexedDB: Remove m_contextStopped from ActiveDOMObjecs

m_contextStopped is equivalent to !getExecutionContext().
So this CL removes m_contextStopped. The only gotcha is
that the context is cleared in the base class *after*
contextDestroyed() is called, so the one place that checked
it synchronously during the call - IDBTransaction -
needed special attention.

The CQ bit was checked by jsbell@chromium.org to run a CQ dry run

[jsbell, 2016-11-03 23:29:01]

This is basically just haraken@'s https://codereview.chromium.org/1745933002/
dusted off, with IDBTransaction tweaked slightly, to see if the bots like it or
not.

No immediate plans to land it.
