pcbnew: When making reference field invisible in Edit Text & Graphics, also makes fields containing ${REFERENCE} invisible

Description

When "Reference designators" is selected in "Edit Text & Graphics Properties", the requested edits also apply to text fields with the value "${REFERENCE}". I expected the latter fields to be included with "Other footprint text items".

Steps to reproduce

1. Select a component that includes additional copies of the reference (e.g., Capacitor_SMD:C_0603_1608Metric).
2. Open Edit Text & Graphics.
3. In the "Scope" group, select only "Reference designators". In the "Filters" group, select only "Only include selected items".
4. In the "Action" group, uncheck "Visible".
5. Select "OK".
6. Observe that both the primary reference designator and the extra copy within the body outline have been rendered invisible.
