Enhanced Grid Paginator: grid loses filter on 'goto page'

[frans.van.nieuwenhoven]

The enhanced grid looses a filter when the page stepper is used to goto a page: all items will display.

To reproduce:

• open dojox/grid/tests/enhanced/test_enhanced_grid_pagination.html
• set page size to 10
• open the browser javasctipt console
• enter: dijit.byId('grid').filter({Genre: 'Rock'})
• this will limit the item count to 13
• click page 2 in the stepper => filter disappears (item count 100)

I applied a fix to Pagination.js in the gotoPage: function(page) function:

change:

    this.setQuery(this.grid.query);

into:

    this.grid.setQuery(this.grid.query);

(In [25404]) Fixes #12832 !strict don't need to keep another query in pagination scope, just use grid.query
