values of custom fileds of version type should be prefixed with or grouped by project name
Steps to reproduce
- create projects hierarchy
- create versions shared with project tree
- create a custom field attached to issues, type version, attached to a tracker of one of the above project
- create a new issue
- whereas shared versions are grouped by projects in "target version" field, versions in custom field are flat (if some versions are the same in different projects, they are displayed indistinctly)
- shared versions in custom field should be either prefixed with project name, or grouped by project name; just like for "target version"
