Bugfix: connection was closed, even when it was never created

Bugreport from: Adriano Machado <adriano.m.machado@hotmail.com>

When only the script is generated and no export is executed, no database-
connection is opend. Nevertheless, the code tried to close it in the
finally-block, which lead to a NPE.
