Fix parsing of old settings with sdktool
Fix parsing of old settings with sdktool

With commit 5aba7fb09504e1a the sdktool started to save id's in a QString
(instead of a QByteArray). Commit b2e3f0262bbf5de4 then adapted also the
parsing. However, this broke the parsing of existing settings still
using a QByteArray.
