fixup openfmri datasets metadata

[yarikoptic]

Currently (some might have been fixed upstream) we have following gotchas while parsing metadata from openfmri datasets (before enabling any custom ones, just bids parser)

• 9 datalad/datalad@2a8dd26 part of Various bugfixes addressing some corner cases while parsing datasets.datalad.org with new extractors datalad#2151
