Subject: [PATCH] ecore-evas-wayland: Fix min/max size calculations

Summary: This fixes an issue for windows which do not set a min or max
size in the properties. This was discovered when running Enlightenment
in a Wayland-Only scenario, and trying to bring up the settings panel
which would cause an endless loop in calculating the proper window
size due to min/max not being set.

@fix

NB: Thanks to Mike for the help in tracing this ! :)
