Unlocked items disappear from list after reverting changes in Commit dialog

[Balázs]

This is a minor issue affecting the list behavior on Commit dialog.

Steps to reproduce:

1. set "svn:needs-lock" on a file
   
2. acquire lock on this file so it is not read-only anymore
3. make some changes to the content
4. open Commit dialog with this file
5. open context menu for this file and select Revert...
6. file disappeared from the list
7. refresh the list by pressing F5
8. file appears again because the user still holds a lock on that

I guess the file should not disappear from the list after reverting changes in this case.
