Fixes issue 104: RemoveFromNavigation and then popping PageModel causes ReverseInit being called on removed FreshBasePageModel, instead of the one being popped.

This is a pull request as discussed here: #104
Please note that there is minor difference in below line, by what we have discussed:
nextPageModel.PreviousPageModel = nextPageModel.PreviousPageModel.PreviousPageModel;
is now:
nextPageModel.PreviousPageModel = nextPageModel.PreviousPageModel?.PreviousPageModel;

I gusess nextPageModel.PreviousPageModel shouldn't ever be null, but I've just added additional null check just to be on safe side.

Also if this is released soon as a NuGet package it would be just awesome :) Do you have any release plan already?

@rid00z any status progress on that pull request?

@rid00z Just wondered if this will be rolled out at any point? As it's causing me an issue currently

Would be nice to get feedback on this. I'm facing this issue as well.

Hello,
I'm facing this issue as well and still have not found a way of fixing it. I am trying to pass parameters so I really need the reverseInit to work properly.. Any suggestions ?
