[Enigmail] can not query passphrase in batch mode

[Stefan X]

That's it! The option "never ask for any passphrase" was enabled. But I 
am pretty sure I never enabled this option. So I created another key 
without a passphrase. I found out that in such case the option is 
automatically enabled by Enigmail no matter if another key with a 
passphrase exist or not. For my opinion this is a bug. Instead Enigmail 
should check at time of key creation if another key with passphrase 
protection exist. If this is the case this option should NOT 
automatically be enabled. Otherwise it could. It would even be better if 
Enigmail checks at runtime if a passphrase is required and does query or 
does not query appropriately. Than such option would be obsolete.
