[one-users] filename in image repository

[Shantanu Pavgi]

Thanks for the explanation Joey.

I updated my OpenNebula install and also started with a new mysql database (essentially fresh install rather than update!). I kept same image repository path after update and it contained image files from previous install. I was getting an error as 'Destination file for image already exists, aborting.', which I resolved by deleting previous image file. I guess changing image name in the template file would have done the trick as well.
