Fix HyperTable

[GoogleCodeExporter]

Doing a put with a specific key name fails in HyperTable:

 Put accepted 1 entities but returned 0 keys.
Traceback (most recent call last):
  File "/root/appscale/AppServer/google/appengine/ext/webapp/__init__.py",
line 509, in __call__
    handler.post(*groups)
  File "/var/apps/gae-dbtest/app/dbtest.py", line 50, in post
    key = greeting.put()
  File "/root/appscale/AppServer/google/appengine/ext/db/__init__.py", line
794, in put
    return datastore.Put(self._entity)
  File "/root/appscale/AppServer/google/appengine/api/datastore.py", line
189, in Put
    (num_entities, num_keys))
InternalError: Put accepted 1 entities but returned 0 keys.

Will investigate.

Hijacking the PBServer reveals the underlying exception is as follows:

The problem is that the application in question is named gae-dbtest, and the 
dash
causes a HQL parse error when the table is to be created (thus causing the put
afterwards to fail).

Works for now as long as the app name doesn't have a dash in it. Need to find a
solution that supports app names with dashes in it.

Lowered priority since the cause of the problem is now known, reassigned to Raj.
