To reproduce:

1. Open HUB;
2. Create a new project;
3. In "Assets" folder create a new one and name it "ArtWork";
4. Double click on "ArtWork" folder and verify that it is empty;
5. From added files move "sprite-sheets" and "sprites" folder to it;
6. Double click on a "sprites" to open it;
7. Verify that it has 11 items;
8. Go back to "ArtWork" folder and double click on "sprite-sheets" folder to open it;
9. Verify, that it has 2 items;
10. Click on a "Open in Search"and select "t:texture" option from the provided list or manually enter mentioned option;
11. Verify that results become displayed on the screen.

Expected result: Search window title and tab title should display 13 next to them - "Search (13)".
Actual result: Instead of "Search (13)" we get "Search (12)" in both mentioned places even though we see "13" next to "All" and next to "Project" tabs.
