Don't assume that page events means the BrowserContext has a page

Browse Source 
CDP currently assumes that if we get a page-related notification (like a
request interception, or page lifecycle event), then we must have a session
and page.

But, Target.detachFromTarget can remove the session from the BrowserContext
while still having the page run (I wonder if we should stop the page at this
point??). So, remove these assumptions and make sure we have a page/session
in the handling of page events.
