Avoid returning an empty Credential object when nothing is populated inside it. Also fix to OpenSAML to metadata base class to stop assuming resolver has to return non-null, per API doc.

Condition rule was also a syntax mistake.
This works fine:
<PolicyRule type="Ignore" xmlns:saml2="urn:oasis:names:tc:SAML:2.0:assertion">saml2:OneTimeUse</PolicyRule>
Normally that's unneeded anyway. Using an empty rule of type="Conditions" defaults to a set of rules that checks time, audience, and ignores the OneTimeUse condition.
I've changed the bug to an improvement request to try and clean up the logging around a KeyDescriptor processed into an empty shell of a credential for verification.

The signature issue is caused by an incorrect namespace on the X509Data and X509Certificate elements in the metadata. Adding ds: to the elements fixes the issue.
I didn't expect that the code would return a Credential object from the metadata with no key inside it. I'll look at that more closely, I might be able to prevent it from returning a credential with nothing inside it at all, which would limit at least some of these cases from being so obscure.
Bug reporter also noted inability to ignore the OneTimeUse condition, checking on that also.
