When running rb-vm-env on Vagrant, would get relative database path in settings_local.py, which would cause some errors. Such as:

"Testing a SFTP-backed bzr repository ... ERROR:root:Could not load siteconfig: no such table: django_site"
Added an import and a path variable to settings_local.py.tmpl

Edited a string that prepare-dev.py wrote into the template.

Performed Review Board unit tests
$cd /src/reviewboard

$./reviewboard/manage.py test
Ran prepare-dev.py to check if it would create settings_local.py correctly.
