Screen set frames update

[slash-bit]

Thank you for sending in a pull request, here's some tips to get started!

This PR fixes #4038 every time setFrame run the page reverts back to Message or Module frame , but not the same frame that was viewed by user before, which could be annoying having to manually switch back to say Status frame. So I have added lines where it would keep the same Frame number that user was one prior to reloading the frames. If that frame still available. There may be some more enhancements needed in the future to accommodate when total number of frames changes ( like enabling/disabling modules or resetting Node DB. For now, testing on T-Echo seems reasonably stable and stays on the same frame while device runs.
