Logging error with initenv

[Manuzhai]

When there is a central trac.ini (in /etc) that enables logging to a file in the environment, initenv fails because it cannot find the file. Makes some sense, since it's looking for a directory that still has to be written, probably.

Failed to create environment. [Errno 2] No such file or directory: '/var/trac/life/log/trac.log'

This is still here! Just ran into it again today.

Assigning to 0.10, as it shouldn't be too hard.

I looked into this some more. I think I fixed the problem, but then trac-admin crashes with a seemingly unrelated exception, see below:

I'll attach my "fix".

[Manuzhai]

Attempt at a fix.

[Manuzhai]

Okay, here's another one that actually works.

Fix #2498 by delaying the database initialization.

The patch didn't quite work for me since some things were still looking for the log before it was initialized. Instead in [3277] I made sure the default config options are loaded for new environments before setting up logging.
