Actually, I believe it is correct. this.__headerRenderer holds the one and
only copy of the qx.ui.table.columnmodel.Basic.DEFAULT_HEADER_RENDERER()
which is used by default for all columns. That test is ensuring that only
renderers which were explicitly set by the user get disposed, and not this
default one which is in use by many columns.
