Revision 1866012

Improved:  Find order screen can't make a search without ship to country
(OFBIZ-11176)
When you search orders on the standard screen [1] you can't unselect a country.
The problem come from the populate country list by countries.ftl who select by default a country without possibility to escape it.
We added a possibility to escape it through variable doNotPreselectDefaultCountryGeoId
