goog.Uri.QueryData.getKeys() should return {!Array}, not {Array}

[GoogleCodeExporter]

Likewise for getValues().

This code:

http://closure-library.googlecode.com/svn/docs/closure_goog_uri_uri.js.source.ht
ml#line1297

can never return a null reference, but it is annotated such that it could. 

This makes using goog.array.zip less convenient, since it requires non-nullable 
arrays as inputs.
