The dojox.layout.GridContainer's default constructor does not check for null or undefined properties

[spidey2099]

UseCase? Extend the GridContainer? and construct it without any properties. This is a valid use case since the properties will be added later. Result: An error is thrown to the effect that props has no values.

Examining the constructor showed that it was checking the properties on the assumption they would exist or be defined. This logic is brittle, since there may well be a case when the properties are not defined. In this case, the default properties should be assigned.

Changed the code to handle undefined properties in the constructor.

(In [20170]) fixes #9470 - create a props object if one is not passed. smaller than the attached patch from spidey2099, though thanks for catching this. \!strict
