In "latest data", popup.php doesn't pre-select the host after clicking the "select" button to choose an application

Step to reproduce the issue :

• Open "latest data"
• Fill the "hosts" field with one host "xxx"
• Click "Filter"
• "Latest data" should display all items of the host "xxx"
• Click on the "select" button next to the "Application" field

Behaviour :

• A new window opens on "popup.php" but the pre-selected host in the top-right isn't "xxx"

Expected behaviour :

• "popup.php" should pre-select the host on which the filtering has been done

Reason :

• When we are filtering on a host and we want to narrow the filtering with an application, the popup should display all applications associated to the host. There is no scenario where we need to filter on a host and then narrow on the application of an other host.

This bug is slowing the usage of "Latest data" because we need to select the host on the "Hosts" field and then a second time on the drop-down menu in "popup.php".
