MvxViewPagerAdapter and MvxStateViewPagerAdapter ignore the presence of view model instance inside MvxViewPagerFragmentInfo

[wh1t3cAt1k]

Steps to reproduce 📜

1. Use tab layout with a view pager.

2. Use e.g. MvxViewPagerAdapter for the view pager. Initialize it with a single-element collection MvxViewPagerFragmentInfo object that contains a view model INSTANCE which cannot be directly resolved from the IoC container (e.g. it is manually created with parameters from the parent page view model)

3. Try to open that page

4. 💥

Expected behavior 🤔

Both MvxViewPagerAdapter and MvxStateViewPagerAdapter should check whether the fragment info already contains the view model instance, and if yes, do not try to Mvx.Resolve that.

Actual behavior 🐛

Crash with a dependency resolution exception.

This needs to be considered in #2440

I would like to contribute under this issue separately, because I don't yet feel the strength to completely clean-up these adapters in the scope of #2440 . I am currently preparing a PR.
