DataTriggerBehavior doesn't work with enum types

[P4bl3r]

DataTriggerBehavior fails on InvalidCastException when Value is set to enum type.

Context here: https://stackoverflow.com/a/49308851/5405256

I have narrowed the problem down to TypeConverterHelper class and I do believe it can be fixed by adding an Convert method overload to TypeConverterHelper:

public static Object Convert(string value, Type destinationType)
{
    var typeInfo = destinationType.GetTypeInfo();

    if (typeInfo.IsEnum)
        return Enum.Parse(destinationType, value);

    return Convert(value, destinationType.FullName);
}

and updating the call in DataTriggerBehaviors Convert method to use the Type instead of Type.FullName

if (leftOperand != null && rightOperand != null)
{
    rightOperand = TypeConverterHelper.Convert(rightOperand.ToString(), leftOperand.
}

Duplicate of #84 although with more context. Maybe someone should create a PR for this? Or are there any design reasons for not implementing it this way?

Thanks @P4bl3r for the investigation! I'm going to close this issue as a duplicatre, but would you like to submit a PR to #84?
