[Libreoffice] fix for fdo#33960 "cross reference to a list number, dot bug" makes sw/qa/complex/writer fail

At least with recent git trunk builds, make subsequentcheck fails in sw with

> 1) checkCrossReferences(complex.writer.CheckCrossReferences)
> org.junit.ComparisonFailure: set reference field format doesn't result in correct field result expected:< 
> 1[.]> but was:< 1[]>
>         at org.junit.Assert.assertEquals(Assert.java:123)
>         at complex.writer.CheckCrossReferences.checkField(CheckCrossReferences.java:120)
>         at complex.writer.CheckCrossReferences.checkCrossReferences(CheckCrossReferences.java:176)

This appears to be caused by the fix for 
<https://bugs.freedesktop.org/show_bug.cgi?id=33960> "cross reference to 
a list number, dot bug," which removes the trailing "." from 
SwNumRule::MakeRefNumString.

The question is, is the below patch (which makes that subsequentcheck 
failure go away) right in adapting the failing test to the new code, or 
does this failure actually uncover unwanted side effects of the new code 
(I'm esp. unsure about changing "A. 1." to "A 1")?
