Traceback when log_file without name

[patrikspiess]

In the fotoobo config you may specify to log to a file:

log_file:
    name: fotoobo.log

If you omit the name: ... a traceback is created:

File "/home/pspiess/projects/fotoobo/fotoobo/helpers/log.py", line 199, in configure_logging
  filename=config.logging["log_file"]["name"],
TypeError: 'NoneType' object is not subscriptable

Instead a warning should occur.

Or configure fotoobo.log in the current working directory as a default. In this way it would still work without warning.
