panel: fix check_resize function

* If panel height is set to 19px, when it starts it does not work. 
* Changing size does not update panel size. New size will be used only next time when panel starts.

Seems these problems are because of panel_toplevel_check_resize function. It is calling size_allocate only when panel width and height is NOT changed.

So if panel height is set to 19px. We get preferred height bigger than current allocation. That means size_allocate is not called. Nothing is updated.

When changing panel height in properties, it does not update too, because of same reason. size_allocate wont be called.

When changing panel from top to left, again size_allocate is not called, nothing changes!

My patch fix these problems and also fix this bug too - https://bugzilla.gnome.org/show_bug.cgi?id=577767
