Reintroduce "Jolla: Remove wizards which do not properly work with SailfishOS"

This reintroduces commit 6e20d1f9d6cbbf01570ae58c18b2610970443e62,
temporarily reverted prior to mer-3.1 merge with commit
7716dd79e488228556655276fe646383f3f0ec03.

BlackBerry wizard display name added because the very first wizard in a
category determines the display name for the category - it would be
empty. This is not an ideal solution as the display name does not get
localized this way. It would not be trivial to fix this properly.

Sailfish app wizard: fix display name

The rationale here is the very same as for the BlackBerry wizard in case
of commit b318d1cd41e658c8360ed3879580f8291aec7aaf. Kept separated for
obvious reasons.
