Wrong message when moving a category

[tzyganu]

Scenario.
In Products->Categories. I'm trying to move some categories around in the tree. Source and destination not important. When moving the second category, the overlay message that should tell me that the operation might take a long time is wrong.

Steps to reproduce:

• Go to Products->Categories
• Add some categories if there are none
• Move one category in the tree.
• In the modal box that appears click OK.
  
• If the move was successful there should be a success message above the name field
• move a second category around (it can be the same one)

Expected result.
I should see the modal box again with the message "This operation can take a long time"

Actual result
I see the modal box with the success message from the previous move.
