All e-mails that should be encrypted got only be encrypted with
the senders public key.
This happened, because $to wasn't an array of addresses but rather
an array of AddressObjects, leading to the following warning, when
sending an encrypted e-mail:

WARN: HORDE [imp] PHP ERROR: array_flip() [<a  
href='function.array-flip'>function.array-flip</a>]: Can only flip  
STRING and INTEGER values! [pid 1982 on line 1352 of  
"/var/www/vhosts/horde.example.com/www/imp/lib/Compose.php"]

However, this also means that all the recipients are omitted and
the e-mail is only encrypted with the senders public key.

This patch converts the address objects to e-mail addresses before
passing them to the PGP library.
