      Description

      It's easy to raise a NPE from orphaned tree windows: Open an alignment, calculate a tree, then close the alignment window and click in the tree to create subgroups.

      Null pointer exceptions are raised like:
      Exception in thread "AWT-EventQueue-2" java.lang.NullPointerException
      at jalview.gui.TreeCanvas.setColor(TreeCanvas.java:527)
      at jalview.gui.TreeCanvas.setColor(TreeCanvas.java:535)
      at jalview.gui.TreeCanvas.setColor(TreeCanvas.java:535)

      The reason is clear - closing the window deletes the alignment.
      The question is: if all windows on an alignment are closed, should any linked tree windows also be closed ?
