Handle nil request in Exchange#navigation_request?

[francisbeaudoin]

Details

As the Exchange object is pushed to the network traffic before assigning its request, it is assumed that the request can be nil in the exchange object.

ferrum/lib/ferrum/network.rb

Lines 355 to 357 in d141613

	exchange = select(request.id).last
	exchange = build_exchange(request.id) unless exchange&.blank?

ferrum/lib/ferrum/network.rb

Line 368 in d141613

exchange.request = request

For that reason, the #navigation_request? method was updated to be nil safe.
