parse empy entries as empty lists so prevent exception in loops

[hitimr]

in some cases conf.yaml may contain nothing under "entries"
yaml parses these as NoneType which are not iterable. This triggers an exception in loops

For example:

func.py

def save_profile(name, profile_list, force=False):
  ...
  for section in konsave_config:
          location = konsave_config[section]["location"]
          folder = os.path.join(profile_dir, section)
          mkdir(folder)
          for entry in konsave_config[section]["entries"]:    #Throws and error
              source = os.path.join(location, entry) 
              dest = os.path.join(folder, entry)
              if os.path.exists(source):
                  if os.path.isdir(source):
                      copy(source, dest)
                  else:
                      shutil.copy(source, dest)

To resolve this we can convert all None-Entries into empty lists recursively before returning the parsed config

This should also resolve #47

Great! I tested it and it works. Thanks for fixing the bug. I was having a hard time figuring it out..
Please add doc strings in your function and use black formatter to format your code as mentioned in CONTRIBUTIONS.md.
