[Evolution] Bug#587849: SQL DB init

[David Woodhouse]

Hm, I don't know why the initialisation is failing. This patch adds some
more information about the failure, which should help us understand.

It also makes the code fall back to the old DBM database, so that
Evolution will actually manage to start up.
