[FIX]fix handling of non-stored passphrases

module: account_ebics 16.0

The non-stored passphrases (passphrase, sig_passphrase) were incorrectly handled
during the INIT cycle:
- setting 'ebics_passphrase_store' during INIT cycle didn't work
- setting the 'ebics_sig_passphrase' during INIT cycle didn't work
