Description:
When creating a mail merge base document and defining data source fields in Word, it also saves information about the file in word/settings.xml.
This can be used to set up data source for example on a different computer with access to the same base document and data source, Word does this.
Writer cannot, and we also lose the information on saving the file as docx (that is worth another bug).

Steps to Reproduce:
1. Open attached docx file in Word and Writer

Actual Results:
Word tries to set up the data source connection, and if successful, it shows the merged data in the form letter.

Expected Results:
Writer should try to set up the data source based on the available information.


Reproducible: Always
