[evolution-patches] fix for #51214 and #57211

[Larry Ewing <lewing ximian com>]

This patch is a bit of a hack with a couple of magic numbers but I can't
find a public way to get the treeview header heights if the widget isn't
realized so I'm not sure there is a better way right now.  If the magic
numbers are off all that happens is a slight offset to it isn't too
severe.  The row height bit is correct.
