Fix exception when accessing empty lock list
This fixes an Access Violation Exception when a WebDAV server says a
resource is locked but does return an empty lockdiscovery element on
WebDAV Propfind. Without this patch, the code only checks that a list
exists, but it should also check if it contains elements before
accessing it.
Fixes tdf#128662
