[Navigation] Wrong ViewModel attached to page when NavigationCacheMode set to Required

[nickrandolph]

Current behavior

App has three pages, Page1, Page2 and Page3. Routing has Page2 as dependsOn for Page3. All pages have NavigationCacheMode set to Required

Nav sequence:
Page1, Page2, Page3, (back) Page2, (back) Page1, Page 3 (this will inject Page2 into backstack), (back) Page2
Page2 has the old viewmodel and is not refreshed to a new instance

Expected behavior

Page2 should have a new viewmodel instance
