[bug] initialize OpenSSL context just once

Do not initialize the openssl context on each call to decrypt.

I'm not 100% sure of the causal chain, but it seems that the
initialization of the osrandom engine that openssl backend does might be
breaking havoc when sqlcipher is calling rand_bytes concurrently.

further testing is needed to confirm this is the ultimate cause, but in
my tests this change avoids the occurrence of the dreaded Floating Point
Exception in soledad/sqlcipher.
