Hi,

thank you for the new p-tree filter feature, just in time for my project, I love it. However...

Current behavior
While in filtered mode the onNodeSelect Event always contains the root node.

Expected behavior
The Event contains the actual selected Node.

Reproduce it here;
https://stackblitz.com/edit/angular-cpkeva
put "child" into filter box and see console always prints root

• Angular version: 7.2
• PrimeNG version: 7.1
• Browser: all
• Language: ES5
• Node (for AoT issues): v11.10.0

I checked the source code and I found the answer. I need to set the key for a node. However, this is not clear within the official docs. Kindly add a note in the filter-section of the p-tree docs. Thank you.
