ucb: webdav-curl: don't use chunked encoding for PROPPATCH

Sharepoint 16 has the same problem with this as with PROPFIND.

But this still doesn't work, trying to add dead properties results
in HTTP/1.1 400 BAD REQUEST now.

In fact, it has additional problems: request 3 properties Foo, Bar, Baz
with one PROPFIND and it complains about Foo, FooBar, FooBarBaz...
