More robust from_csv behavior for GridResultContainer

[t-ober]

1. When given a wrong path the GridResultContainer returns "Can't determine simulation end .. " we should hint that this could be due to a wrong path
2. If the path is wrong but the folder contains a folder called rawOutputData we should use that path

Check if such changes should be implemented for the ResultDicts. l
