Fix bug in monitor page

In commit b7fd75b2dd202f2516f9188e342eccc8a15ae6ab the component with id `printerTypeSelectorRow` was removed. As the `tabBar` element was anchored to this component the monitor page was broken. Fixed by anchoring to the component that was previously above `printerTypeSelectorRow`.
