Bug description

Steps to do:

1. Go to stories page
2. Choose Stories Privacy from Menu
3. Click on My Story to go to Privacy Settings.
4. Click on any of the options from All except... or Only share with..., which will navigate us to the ContactSelectionListFragment.

Issues:

1. The Select All button does not update the UI.
2. The done button should be visible only if the Selected item is more than 0. (Logically expected behavior)

I am ready with a PR, please approve this improvement and assign this issue to me.

We can optionally add the Header action of Unselect all. When we click on Select all (which I have fixed now), we can change that option to Unselect all. by checking a variable from the ViewModel named isAllSelected.
And if unselect all clicked, we reset the list and the isAllSelected. and HeaderAction is again reset to Select All.
If user decides to click on the chip or deselect one contact, then we can check if list is empty || isAllSelected is false. then change the HeaderAction back.
