Qnx: Correctly restore BlackBerry kits from previous QTC builds

* When setting autoDetection source to old pre-existing kits, the
setKitsAutoDetectionSource() was mistakenly comparing the kits device type id
to QNX_BB_CATEGORY_ICON instead of QNX_BB_OS_TYPE.

* The setKitsAutoDetectionSource() method was called earlier before
the API levels are loaded/restored, so previous BlackBerry kits
were not updated (i.e auto detection source is set).
