Bug: Title cannot be empty

[mobile-pablo]

Describe the bug
When u are creating tile u cannot have title empty despite nullability.

To Reproduce
Steps to reproduce the behavior:

1. Create PageViewModel without title

Expected behavior
Views should be displayed

How to resolve
Make title widget nullable completly and if its null pass a container
Also change naming to something better because ViewModel says like its Fragment ViewModel which is isint, its Tile
ItemTile or PageTile
