Page view is triggered automatically on init

[sami-ft]

When calling init() there's an option to pass pageViewParams and the page view event gets triggered automatically.

However, the page view event can only be triggered once, which means we can't trigger the event externally.

We'd like to be able to trigger the the page view event manually and have more control on what we pass to it
For example, we're getting the consent data with the new PG ads, we'd like to only get the consent once before forwarding the page view event, it would slash the need to gather consent into n-tracking and duplicating the effort of gathering consent data.

Once PG is the enabled on ft.com, we will make a change to n-tracking so that the page view event can be triggered independently from init()
