[xmlsec] hybrid encrypted data for multiple recipients doesn't find keys in Keymanager after first during decryption

I recall that someone else also had problems with key names in
xmlsec-mscrypto. I believe that in this case, key name is either
0) key name assigned by you when you added key to the keys manager
1) cert id (key/cert is in MS store)
2) full subject dn (key/cert is in MS store)

The key name you use

<KeyName>de, TU Darmstadt, FB20, Christian Valentin-6E</KeyName>

does not look like 1) or 2) thus you have to put key into keys manager
yourself. Try to dump keys manager and check that the key is there.
