[Bug]: Litmus 0.14 not passing depending on WebDAV endpoint

Bug description

We currently only test against litmus 0.13, but https://github.com/notroj/litmus/commit/4a6c2775cc06bd0977779ee53ab9dfbeef8bd5fb introduced a new check which breaks our litmus-v1 but not our litmus-v2 tests. There has to be some inconsistency in the error handling between the used WebDAV endpoints.

Steps to reproduce

1. Use litmus 0.14
2. Run make URL="http://localhost/remote.php/webdav" CREDS="admin admin" TESTS="basic" check
3. Run make URL="http://localhost/remote.php/dav/files/admin" CREDS="admin admin" TESTS="basic" check

Expected behavior

Both test runs should pass, but the second one fails with 5. put_no_parent......... FAIL (PUT with missing intermediate collection gave 404, MUST be 409 [RFC4918:S9.7.1]) while the first one passes that test successfully.
