Frameworks: slimrecents: allow closing recents in middle of the open animation

As reported by Tejus Kandachar steps to reproduce:

Press Recents button and very quicky tap on one of the apps in the recents list,
just as recents list is sliding in. If done fast, the app opens but recents screen does not close.
If done normally it slides away as expected.

Fix it with allowing to close the pannel as well on animation in state.

Frameworks: slimrecents: call app details screen correctly

So feedback shows that we only have 2 bugs. For the one patch is up. The other
one is fixed here.

two problems

1. Longpress opened the detail screen twice and wrong

2. It shows up in the task list which it should not. Going inline
   with the AOSP implementation of it.

use TaskStackBuilder to call it proper with our animation on top.
