RFR: 8296083: javax/swing/JTree/6263446/bug6263446.java fails intermittently on a VM

Test intermittently fails in VM citing "Tree is not editing". Seems to be problem with mouse clicks not getting registered properly..
Similar test test/jdk/javax/swing/JTable/6263446/bug6263446.java is not affected, so made the test similar to it by using same safeguard using Robot.waitForIdle() and modifying clickpoint to tree cell midpoint.

Several iterations of the test pass in the OCI VM and all other physical platforms (link in JBS)
