BUG: duplicate zips created on download

[omero-qa]

Steps taken:

• touch /tmp/a.fake
• echo sizeX=4000 >> /tmp/a.fake.ini
• echo sizeY=4000 >> /tmp/a.fake.ini
• bin/omero import /tmp/a.fake.ini
• In Insight click on download and try to save in /tmp
• Here I'm not sure what happened, but something like click twice quickly? Get asked if I want to rename since a.fake exists??
• In any event, I chose b.zip as the name. Then I got an error that b_(1).zip existed?! Note: b.zip _also_ existed but not from me.
