I added an assertion that m_currentRequestId is Nullopt when dispatch() is called, but this should not hold if dispatching a backend command while debugger is paused. I will remove the assertion and add proper scoping for all dispatch() branches.

This caused inspector/dom-debugger/node-removed.html to crash reliably, rather than flakily due to some other JSC bug.
