8042054: JTree.updateUI uses out-of-date item size information

[prsadhuk]

JTree.updateUI calculate item sizes from the cell renderer, but it doesn't call updateUI on the cell renderer until afterwards. This leads to incorrect size calculation, which is observed when we switch from one L&F to another where it is seen that all tree items are slightly too cramped, with too little space between rows and text are abbreviated.
Fix is to ensure JTree.updateUI update the cell renderer before updating the UI.
CI testing is ok..
