Fix: Handle missing output file
If no output file is found, return nil.
Previously, it would try to find the output file by doing a recursive glob search in the config dir. It would then try to open the file for reading regardless of whether any file was found.
I ran into this when I fired up oxidized for the first time and tried to access a switch config on oxidized-web before it had a chance to collect it.
In this scenario, you get a stack trace on the switch config page (e.g. `http://oxidized.example.com:8888/node/fetch/switch-001.example.com`):
