[PATCH manager] ui: guest cmd menu: don't close it when error dialog is clicked

[Dominik Csapak <d.csapak@proxmox.com>]

If for some reason the API call fails (wrongly cached permissions,
invalid storage configuration in the guest, etc.) interacting with the
error popup normally steals focus from the context menu and closes it.

Even in such an 'invalid' configuration state, we should not deny
users access to the cmd menu in this way, so prevent the context menu
from hiding until the error message is closed.

The take snapshot button is disabled by default, so without the result
of the API call it simply does not get enabled.
