LSM: Does not reconnect after virtuoso restart

[hylkevds]

When virtuoso is restarted LSM does not reconnect to virtuoso. I noticed because GSN could not log in any more.

To reproduce:

• start the platform
• push data through GSN to confirm everything works
• stop and start virtuoso
• try to push new data through GSN.

Security module output:
