Don't throw an error when receiving a message from popup

[private-face]

@cliqz/adblocker-webextension breaks message passing from popup to background page. handleRuntimeMessage always throws an error here, because sender from popup never contains tab and frameId:

adblocker/packages/adblocker-webextension/adblocker.ts

Lines 305 to 315 in f4c7ce4

	if (sender.tab === undefined) {
	throw new Error('required "sender.tab" information is not available');
	}
	if (sender.tab.id === undefined) {
	throw new Error('required "sender.tab.id" information is not available');
	}
	if (sender.frameId === undefined) {
	throw new Error('required "sender.frameId" information is not available');
	}

This stops other async message listeners from executing.

This PR fixes it by checking for correct message action before sender.tab/frameId.

Looks like there is an issue while publishing the package, I'll have another look over the weekend.
