Wrong title for newly created default changesets in the Uncommitted group
When a fresh Synchronize operation is started from a perspective other than Team Synchronizing, the description of the default changeset is set to an old description instead of being auto-generated like when using the Create New Change Set command.
This is tied to #516 (closed) in that this is the result of crust building up in the preference file. The root cause is again the preferences API not allowing the removal of preference nodes.
