Why do we need this check inside SerializedName constructor, if there is name?

[idchlife]

I encountered this part when using PhpStorm with PHP Annotations plugin, when I wrote name="my_preferred_name" and got error "value" key undefined after opening my app.

So, if there is public property $name, why is there value? How about PR for this thing, whatcha guys think if I manage one?

This check is needed when writing things like @SerializedName("the_property_name"). But of course, this should check, whether the 'value' key exist in this case.

This is ment to make obligatory the first parameter of the anotation
