python error on QGIS exit

[gioman]

Frequently when exiting QGIS a python error from geogig plugin is thrown, even when during session no Geogig related work/operations were made:

Traceback (most recent call last):
  File "/usr/lib/python2.7/dist-packages/qgis/utils.py", line 388, in unloadPlugin
    plugins[packageName].unload()
  File "/home/giovanni/.qgis2/python/plugins/geogig/plugin.py", line 96, in unload
    sys.excepthook = self.qgisHook
AttributeError: GeoGigPlugin instance has no attribute 'qgisHook'

Seen also after upgrading the plugin on Linux.

And now also seen

Traceback (most recent call last):
  File "/usr/lib/python2.7/dist-packages/qgis/utils.py", line 388, in unloadPlugin
    plugins[packageName].unload()
  File "/home/giovanni/.qgis2/python/plugins/geogig/plugin.py", line 92, in unload
    QgsMapLayerRegistry.instance().layerWasAdded.disconnect(trackLayer)
TypeError: 'function' object is not connected

on exit (and again on Linux, so not an officially supported platform).

Seen on update also on Windows:

AttributeError: GeoGigPlugin instance has no attribute 'qgisHook'

should be fixed now, I removed the wrong line that was causing the error. Can you confirm?

Not seeing the python errors anymore after the upgrade to the latest code, so the fix is confirmed.
