- startplasma: Also set environment variable when it is not currently set
qgetenv returns a null QByteArray when there is currently no such variable. A null QByteArray is distinct from an empty one. However, operator!= will treat them the same. Therefore it's impossible to set an environment variable to an empty value.
Explicitly check for null and also qputenv it when this is the case.
