Subject: Store filesize before encrypting the file

Store filesize before encrypting the file

This currently applies only for async uploads.

Otherwise we would send the size of the encrypted file and the data of the unencrypted file.
The encrypted file is usually larger than the unencrypted one. So the browser expects more
data and aborts the download because it thinks it didn't receive all the data.
