End of line character in dataset name causes problems in the metadata operations

There is an end of line character in https://data.anc.plus.ac.at/bids-datasets/openneuro/ds003126/-/blob/4c589b4f38d44955bbb8f8835e06ffa38ed13a2f/dataset_description.json#L17, which breaks loading metadata into the database. I will remove it.
