NPE on startup of JOSM

[rickmastfan67]

Just saw this in the command line of Java. Didn't show the bug reporting screen. Thankfully I was able to copy/paste the info from the console.

Doesn't seem to completely break JOSM, but does seem to prevent the opening screen that shows the recent major changes on from loading, as I was able to open a saved file.

I attached a patch that moves the construction of the GettingStarted panel later in main. This should solve that dependency problem.

In the long run I want to solve this by getting rid of Main.panel (which has only few uses in plugins - most of which are repaint() calls).
