Improve info error messages introduced in 74b72df9.

Browse Source 
- Add detail to errors when info files are loaded with incorrect encryption settings.
- Throw FileMissingError rather than FileOpenError when both copies of the info file are missing.
- If one file is present (but errors) and the other is missing, then return the error for the file that was present.
