Exclusive keyword causing problems because of missing path

[EHJ-52n]

The keyword to mark subsite exclusive resources implemented in #44 seems to cause problems in my current setup.

The keyword created in

geonode-subsites/subsites/apps.py

Line 51 in f1fcd4f

HierarchicalKeyword.objects.get_or_create(name="subsite_exclusive", slug="subsite_exclusive", depth=1)

has an empty path resulting in the following error, if new keywords are added:

The workaround is to delete the keyword "subsite_exclusive" and create it again manually, which results in the path 0001. This allows the addition of new keywords.
