Expected MgInvalidArgumentException? is not thrown in MgFeatureQueryOptions::AddFeatureProperty?() when adding an empty property name.

Step to recur:

1. Construct a MgFeatureQueryOptions? object.

2. Call AddFeatureProperty?() with an empty string as argument.

Sample code:

MgFeatureQueryOptions? featQueryOpt = new MgFeatureQueryOptions?();

//MgInvalidArgumentException expected.

featQueryOpt.AddFeatureProperty?("");

Expect result: MgInvalidArgumentException?

Actual result: No exception thrown
