Updating the name of a Global Issue Type does not update it's name across any Issue Type Schemes it may be associated with

Steps to reproduce:

1. Administration > Issue Types
2. Rename 'New Feature' to 'Blahhh'
3. Switch to 'Issue Types Scheme' tab
4. Notice that the old name still exists

This affects the GUI in various other locations and is causing some confusion among users. Restarting JIRA fixes it.

Alternative workaround: click "edit" next to the affected issue type scheme, then save it without making any change. The issue types contained in the issue type scheme will now be updated with the correct values
