Updates the properties and fields of an existing translation unit if the source and target segments are unchanged or adds a new translation unit otherwise. If the provider doesn't support adding/updating, the implementation should return a reasonable ImportResult but should not throw an exception.

The translation unit should be initialized in a previous call to the translation memory, so that the ID property is set to a valid value.
