Add test to verify APK signing history returned in rotated order

SigningInfo#getSigningCertificateHistory should return an APKs signing
history in the order of rotation with the original signer at index 0
and the current signer at the last index. This commit adds a test to
verify getSigningCertificateHistory returns the signing lineage of
an APK signed with multiple signers in the history in the order of
rotation.
