server log

Description of problem:
When uploading a CLI script during creation of notification for an alert definition, exception is thrown to the server log and operation fails. This applies only to certain scenario (see repro steps)

Version-Release number of selected component (if applicable):
Version: 4.8.0-SNAPSHOT
Build Number: ff37cd9

How reproducible:
Always

Steps to Reproduce:
1. create two repositories named i.e. "First" and "Second" (Administration->Repositories->Create New)
2.add a notification (cli script) to some alert definition:
  a. pick some resource (i.e. platform)
  b. go to Alerts->Definitions->New
  c. go to Notification tab->Add
  d. pick a Cli script as a notification sender
  e. pick "First" repository
  f. upload some js file, use version 1.0 -> notification is added successfully
3.try to add another notification:
  a. pick a Cli script as a notification sender
  b. pick "Second" repository
  c. try to upload the same file with the same version

Actual results:
Error uploading file [File]
ERROR: duplicate key value violates unique constraint "rhq_package_version_idx"
see attached server.log for complete exception

Expected results:
File is uploaded to the "Second" repository

Additional info:
It seems that the RHQ is not able to store the same file with the same version into two different repositories.
