This reverts commit f16fbaf1.

slapos.cookbook:softwaretype tends to lowercase keys in each section, which
has been undetected due to using lowercase references of slaves in the tests.

By restructuring information in the sections, and putting slave references
inside of dumped part of information, now the slave reference case is kept.

Also real care was taken to stabilise published lists by sorting them, as it
also slipped, that they could be unstable.

Tests has been updated to catch this issue, also other tests were fixed, as
they had wrong assertions.
