Summary:
Otherwise we have a gap during load (waiting querying kactivities))
between screen pool being created and us connecting to the screen
changed signals, which in turn are used to update screen pool.
In particular the primary screen can get out of sync between the current
state and the screen pool.
Test Plan: Based on Christopher Feck's research and initial patch

at startup, if a screen id is missing from the screenpool mapping
containment::screen() will return -1 for a moment in the startup
phase even if it has a valid lastScreen
populate mappings of eventual missing stuff at screenpool ctor
make sure destroyed containments don't get assigned a view

Summary:
We used to append them, but that didn't work well and was crashing plasmashell
on fresh start.
A default desktop would be created alongside with the one provided by the
layout instead of replacing it.
If a layout wants to provide an additional screen for a desktop in the secondary
screen, it should specify the screen.
Test Plan:
Now the plasmashell tests pass. In fact I noticed it was broken due to an e-mail
Jonathan sent me that the test on neon was timing out. The test in neon will
freeze when the test crashes. Probably something to look into.
It can be reproduced by running:
```
xvfb-run -a --server-args="-screen 0 1024x768x24" dbus-launch --exit-with-session <exec>
```
Where `exec` is the process we need to run.
Now the test passes.
It's a crash that I had reproduced locally in the past. I can't now.
