error in TableSnapshotGenerator

[flyingtof]

Hi

I'm using liquibase-hibernate3 version 3.3
I encountered this problem.

In class liquibase.ext.hibernate.snapshot.TableSnapshotGenerator. On line 82
primaryKey.setName(table.getPrimaryKey().getName());
, the "table.getPrimaryKey()" statement returns null, ans thus it throws an NPE and the liquibase operation fails.

When replacing this line with
primaryKey.setName(column.getName());
It work better (but not sure at all of potential negative impacts)

Thank's for your job!
