Saving a title token as blank

[russell-kitchen]

Description

A client wishes to not have '- SiteName' on certain pages only. It seems this isn't natively possible, so the solution was to add a space in the secondary token and save, which works. However, due to Craft's autosave/backup functionality, a second after adding the space it reverts to the default '- Sitename' string. You have to be faster on the save than Craft is on the backup in order to get this to work.

Steps to reproduce

1. Replace '- Sitename' token with a space on an entry edit page
2. Wait a second for Craft to backup the changes
3. See that the default token has reappeared
