Issue Summary

When using JC2C to migrate Jira projects from source cloud to target cloud, there is a misleading error shown on the "Check from Conflicts" phase.

However, there is no JSM product installed on the source instance. Even if the customer had installed, it may have been uninstalled subsequently.

Steps to Reproduce

1. Add JSM product on source cloud site
2. Create a JSM project and add issues, customers, and so on
3. Delete the JSM project
4. Remove the JSM product from source cloud site
5. Start a new migration plan
6. Navigate until "Check for Conflicts" page

Workaround
