Bug 761140: importing gimpui module causes plugin query failure

After commit f51acf3bfb the python console no longer
initialized gimpui, because it is no longer part of module
initialization.

If the plug-in is run noninteractively and it imports
gimpui explicitely it is now necessary to call gimp_ui_init ()
at the right time
