Fix potential NPE and warn if trustall is being used in the exporter

[brunobat]

Analysis revealed the possibility of some null pointer exceptions (NPE) and an index out of bounds.

Also not warning when trustall is being used in the exporters connection.
Even if it's not the default, it was flagged as a security risk and a warning is now emitted. A test was added to make sure the log line is there.
