Code fix error in CC0014 TernaryOperatorAnalyzer (assignment) 

Code fix for CC0014 TernaryOperatorAnalyzer is not compatible with += operator in VB code.
Example:
Original code:
          If values = String.Empty Then
            values = valueString
          Else
            values += ", " & valueString
          End If
Fixed code:
          values = If(values = String.Empty, valueString, ", " & valueString)
