Fix context update bug

[ndricimrr]

Description
Navigating inside of a micro-frontend (ex: Angular based) using its internal angular routing is facilitated using withoutSync. However, even though the navigation is successfully prevented with this function, there seems to be no context update upon internal navigation.

Changes

• Have the Core send a message to the iframe when withoutSync is activated. An additional withoutSync parameter is added. The rest of the message body is the same.
• Catch the event message on the Client side in the lifecycle manager and handle it differently if withoutSync is activated:
  • Omit navigation if withoutSync is present
  • Add extra parameters to the context as useful information for the virtualTree structure

How to test

1. Open e2e-test-application and navigate to projects/pr2/developers
2. Click the withoutSync link and check the console for Context Changed print outs.
3. A context update event is fired and the printed context should have pathParams and viewUrl as properties.
