  Remove incorrect assertion in BrowsingContextGroup::removePage

Reviewed by Charlie Wolfe.

We currently don't call BrowsingContextGroup::addPage until the UI process
receives a message that the main frame has been created.  If window.close is
called before then, many API clients will deallocate an opened page immediately.
Add a test for this case and remove the invalid assertion.
