Parley: Fix Coverty Scan ID 1342591 - Dereference before null check
Review Request #128128 - Created June 8, 2016 and submitted
The m_translation pointer member of MultipleChoiceWidget class is now inititalized in constructor and missing null pointer checks before usage were added.
in an application we can also use nulltpr, since we do not have such strict compiler support requirements like KF5; and actually nullptr is already used in Parley code
that looks awkward, at least uncommon to use references here; I wonder why there is a method setMultipleChoice(...) which is commented out... maybe a code improvement in another review? :)
