Fix T85716: "Applied Modifier:" report hides more important message

Since "Applied Modifier" was always added last, it obscured more important
messages when using the shortcut to delete modifiers. The purpose of the
report when using the shortcut was to make it clear that something
happened. Since another report does that anyway, only display the
"Applied Modifier" report if the report list length hasn't changed.
