Cli importer qa report dev 4 4

Fix issue with command line importer not sending error reports to QA application (cause: the CLI args were not propagated to the in-memory configuration).

To test the resolution: 
- attempt to upload an invalid file (eg. http://qa.openmicroscopy.org.uk/qa/feedback/7336) with the `--report` option enabled. 
- the INFO log output should indicate `Sending error report (<number_of_errors>) ...` prior to filing a QA ticket.
