[DF] Issues with RDataSpec paths using EOS #17449

Description
It seems there is some mismatch in the paths when creatind RDataFrame objects using RDataSpec when the input files are stored on EOS.
The corresponding method fills a SampleMap with the identifier filepath+"/"+treenamefor each file in line 443 of the RLoopManager class.
Later, when running the TreeReader, the file linked with the TTree is compared to this metadata entry in line 781 of the same class. When the input file is available locally, this works fine but with files located on eos it causes issues.
The filepath of the format /eos/home-w/name/my/path/file.root is translated to the filepath associated with the TTree later but has the format root://eoshome-w.cern.ch//eos/user/name/my/path/file.root. In summary, the code looks for the key root://eoshome-w.cern.ch//eos/user/na,me/my/path/file.root/reco in a map containing the key /eos/home-w/name/my/path/file.root/reco which leads to a runtime error.
