Duplicate detection doesn't work for absolute paths

[przemekrcloudity]

Hi! In the previous issue, I stated that provided configuration works. It turns out that the duplicate metadata detector was running fine with AND without a specified configuration. The difference that made the configuration work for me was the fact that second time I run duplicate detector with relative path instead of absolute path.

After some investigation, I found out that duplicate detector adds ./ prefix to path, which makes globs correct but at the same time makes absolute path incorrect.

I think it could be good idea to separate parameters used for files and globs definitions or add note in files parameter help text that it should specify glob pattern.
