We use https://qa.staging.openmicroscopy.org to test this PR
Test 1
 * Try to import  a faulty image e.g. squig/data_repo/test_images_bad/multi-image-pixels.ome.tif . 
 * Test logs report i.e. --logs . Check that the corresponding entry has a .log file (not .zip)
```
bin/omero import -s localhost -u root -w omero -p 4064  --report --logs PATH_TO/multi-image-pixels.ome.tif
```
 * Test upload report --upload Check that the corresponding entry has .zip
```
bin/omero import -s localhost -u root -w omero -p 4064  --report --upload PATH_TO/multi-image-pixels.ome.tif
```

Test 2
 * Try to import squig/data_repo/test_images_broken/broken_images_scenario/fails_at_processing/wrong-light-source-mk3.ome
 * Test logs. Make sure that there is no NPE in console and that the error is submitted. No log file
 * Test upload. In that case, only the file should be upload since the log is not available.
