Related tdf#88502 Add default XCommandEnvironment to ...

... Content::getResourceType

During WebDAV operation the css::ucb::XCommandEnvironment is almost always
needed.
Depending on the operation, sometimes the client doesn't set it, in order
to disable the exception processing that takes part in
ucbhelper::cancelCommandExecution.
