Switch order of digest and digest encryption algorithm
Sometimes "digest encryption algorithm" would be "RSA" which would match
a Signature provider, but its default setup would be whatever the
provider chose. This works fine with newer algorithms that have a
specific OID for their signature format (e.g., ECDSA and SHA256), but
not with algorithms that just have a generic OID for all possible uses
(e.g., RSA). Stock Android never hits this problem, because nothing
registers a "Signature.RSA" provider, but Spongycastle does so using
JarURLClassLoader after inserting Spongycastle causes a problem.
Flip the order of tries to make this work more uniformly with more JAR
and provider combinations.
