[xml generation] Update import command

BZ: 116653

The command getDomainsXML was renamed to getDomainsWithSettingsXML.

Use getDomainsWithSettingsXML instead of getDomainsXML as the default
import command. Fallback on deprecated command getDomainsXML if the
new command getDomainsWithSettingsXML does not exist.
