md5 as own value or as description

[TRox1972]

On some of the extractors I've seen that in _TESTS, the md5 is sometimes written as 'md5': 'e43f2842df668f92870ea39d3304f1ee while it is sometimes written as 'description': 'md5:e43f2842df668f92870ea39d3304f1ee'. Which is better to use?

'md5': 'e43f2842df668f92870ea39d3304f1ee' is the MD5 of the downloaded video file (in tests only the first 10KiB of a file is downloaded) and 'description': 'md5:e43f2842df668f92870ea39d3304f1ee' indicates the MD5 checksum of the description field is e43f2842df668f92870ea39d3304f1ee. They are used for different purposes.
