Fix initial TTL on set

[ajermaky]

The initial TTL fetch for the set method was getting the default TTL set in the options. This is because a call to _getTTL was made after encrypting the session object, which meant the checks on the cookie were now invalid.

Moving the call to TTL before the encryption
