DiskProbe crashes when choosing Attributes menu > [attribute] after this attribute was previously deleted

[cafeina]

Steps to reproduce incident:

Open a file with DiskProbe that has attributes, these populate "Attributes" menu. When clicked any of them the atribute editor pops up. There, if user deletes the attribute with menu Attribute > Remove from file, the attribute is removed from file (pop up window is also closed), but the Attributes menu of the parent window does not remove the now non-existent data. That allows the user to be able to select that attribute from menu, but trying to open something that does not exist anymore makes the app crash.

Comment from submitter:

I think the problem here is that the menu is not refreshed every time a change of attributes occurs, but it keeps with the list that was automatically populated from the start.

Environment:

Tested with live USB of hrev54154_31 x86_64 (test release of beta 2 offered here: ​https://discuss.haiku-os.org/t/help-wanted-r1-beta2-boot-hardware-testing/9511) in bare metal.
