When going back from an Item to the List of Items, the current filter should be reapplied

[vletroye]

The problem

To edit an Item in openHab3, we have to search for it first, via the Settings > Items of the Main UI.
To search for it, we enter its name in the Search box.
Once we have searched and found the item, we click on it to see the details (open the Item).
Once done, we click on "Back" to go back to the list of Items.

But once back in the list of Items, although the name used to search for the item is still there, the page immediately displays the full list of items. One has to modify the name in the search box to reapply the filter.

It would be convenient that, when coming back to the list of Items, it is automatically filtered with the name still available in the Search box (Especially when one intends to edit all Items with the same name). In other cases (when one intends to edit other items), one has anyway to type another name (changing or removing de facto the filter).

Expected behavior

When going back to the list of Items, the name typed in the Search Box should be reapplied as a filter instead of showing the complete list of Items.

Steps to reproduce

1. Go to the Settings > Items menu of openHab3
2. Search for an Item
3. Open that item
4. Click on Back

You can see that the name of the item, typed as step 2, is still in the search box. But the list is not filtered anymore.
(Actually, it's filtered when you just come back to the list but within 1 second, it's unfiltered)

Duplicate of #861 which was fixed in 3.1.0, unfortunately due to incompatible code changes it couldn't be applied to the stable 3.0.x releases. I'll consider it closed nonetheless.
