DB AssertionFInder connection() takes 0 positional arguments but 1 was given

[mhennessy8]

The last update to conceptnet5/db/query.py (b744e34) changed the "connection" attribute in the AssertionFinder class to be a property. However, the execution of line 231 cursor = self.connection.cursor() throws an error because the connection property is missing the self argument. This issue can be resolved easily by changing Line 128 def connection(): to def connection(self):.

As it stands, this bug breaks the master branch of conceptnet.

I'm experiencing the same issue. @mhennessy8's solution indeed fixes this issue.
