Fixed SfxDocTplService_Impl::setTitleForURL to keep all streams.

After commit 117fdb98, the setTitleForURL only wrote the meta.xml file
to the odf container, dropping all the other streams. Use storeToStorage
as in the old implementation to fix the problem.

Even though marginal, this problem is important for templates renaming.
