[Evolution] Bug#587849: Handle NSS init errors better

[David Woodhouse]

This code isn't handling errors very well. First it ought to report the
error more coherently so that we know what went wrong, and then it
should fall back to using the old DBM database instead of just failing
completely.

This should fix those complaints, and I'd be very interested to know the
output, which should explain _why_ the SQL database is failing to
initialise.
