Title: Never ignore populate()

If populating is requested while other populating is in progress, don't
ignore it, but populate after current one ends.

Consider scenario:

1. user starts typing into filter toolbar: "foo"
2. grid starts refreshing via ajax
3. user keeps typing: "foobar", but triggered reload is ignored, as grid is already loading
4. grid loads and is incorrectly filtered
