Fix project list match with directory name

This change reverse the directory name creation to find
projects name back from projects.yaml.

Directories were created using:
for project in projects.keys():
  os.mkdir(project.title().replace(' ', '_'))

Also fix DATE_MAX to match Liberty-Mitaka timeframe.
