Change wallet relocking code to set the relocking time relative to the local machine's current time, instead of blockchain time (which screws up automated tests that operate with the blockchain clock set far in the future or far in the past)
CLI was incorrectly reporting wallet as being closed because path string to wallet file wasn't set to correct state in create_file. Code is still a bit strange, as we leave the wallet open at end of create_file and then call wallet::open.
Fees can be paid in any asset with an ask
