Workaround for GCM IV length issue

GCM implementation was ignoring IV bytes except first 12B. The issue has
been fixed but we need to support the decryption of the data encrypted
the old way.

This workaround retries the decryption with an IV truncated to 12B if
the decryption with original IV length fails.

Unit-test included.
