If a body arrives with an OPTIONS request, and it contains an

<options> tag, as defined by RFC 3253, and we don't recognize the
option as a builtin one, then we pass that off to the versioning hooks
of the DAV provider for it to process. However, we neglected to check
whether the provider actually *had* versioning hooks first.

The fix: simply check for versioning hooks before using them.
