[gimp] libgimpwidgets: return TRUE in GimpColorProfileChooserDialog's "delete-event"

    libgimpwidgets: return TRUE in GimpColorProfileChooserDialog's "delete-event"
    
    Otherwise the dialog is automatically destroyed when e.g. pressing
    Escape, which the code doesn't expect, leaving dangling (crashing)
    ponters around.
