[Tablet Support M2] Issue 10863 - Fix order list reload on search view expand

[jd-alexander]

Closes: #10863

Description

The issue encountered in the OrderListFragment was that the order list would not show any results after a search query didn't find items and it was cleared.

The solution implemented in the onQueryTextChange method now ensures that viewModel.loadOrders() is only invoked when there is an actual change in the search query from a non-empty to an empty string. This means that the full list of orders is reloaded only when the user clears the search input.

Testing instructions

1. Go to orders list for a store that has some orders
2. Search for something that will return a result
3. Use X is search bar to clear search results
4. Edit order in right pane
5. Notice that going back to the order's list shows all the items.
