Patch to fix a bug

[Joachim Ansorg]

Hi!

After adding a new item to the "Others..." group of the doctree I noticed that
the icons apper _twice_ until you restart KDevelop.

Here's the patch to fix this. It implements clearing the child items before
adding all items again.

The patch was created with diff -u

Thanks!
