Ask for password before adding entry instead of after (#951)

* ask for password before adding entry (#799)

This fixes #799 because previously it would allow you to create an
entry using your editor and then attempt to open the journal. This
behaviour is fine for unencrypted journals but with encrypted journals
it means that if you get the password wrong three times then the entry
you just wrote is lost.

Swapping the order around so that the entry is opened first in the code
and then the editor is added means that this can't happen.
