reports: remove log in dispose() to avoid IllegalStateException

This fixes the Exception below. The exception is caused because during
shutdown the o.e.tc.incubator.analysis.core (for reports)
Activator.stop() method is called before and the plug-in is removed from
the static list of activators.

Remove the log statement to avoid this exception during shutdown.
