StreamExecutionEnvironment#addSource(SourceFunction, TypeInformation) doesn't use the user defined type information

      Description

      class MySource<T> implements SourceFunction<T>, ResultTypeQueryable<T> {
       TypeInformation getProducedType() {
         return TypeExtractor.createTypeInfo(SourceFunction.class, this.getClass(), 0, null, null);
       } 
      }
      
      DataStream ds = tEnv.addSource(new MySource(), Types.ROW(Types.STRING))
      

      The returned TypeInformation of MySource is GenericTypeInfo, not the user given RowTypeInfo.

      It seems that StreamExecutionEnvironment#getTypeInfo doesn't use the user given typeInfo in the highest priority.
