[Tracker]: Wrong behavioor when using the DEL key while on "edit file name" mode.

Tracker in list view mode.

• Select a folder, hit F2, use arrows keys to place cursor at the start of the name.
• Hit DEL key.

Instead of removing the first character of the folder's name, the hole thing gets sent to Trash.

This can cause serious data loss if a user doesn't figures out what happened with that "disappearing" folder/file before emptying the Trash.
