Adding author via webapp breaks bids-validator

[manuelakuhn]

Using the webapp functionality to add an author adds a dictionary to the author list. Besides that author dictionaries are not defined in the BIDS format (Authors should be an array of strings), it results in an internal error in the container of the bids-validator.

$ datalad create -c hirni sourcedata
$ cd sourcedata
$ datalad webapp --dataset . hirni

-> Edit study metadata\ -> Add author "first_name family_name"

results in:

$ git diff HEAD HEAD^
diff --git a/dataset_description.json b/dataset_description.json

Thanks!

Need to double-check BIDS, since I'm pretty sure I produced valid records that way. May have changed since (if only by being more specific in what's allowed there).

Note: Such a change would require to adapt the webapp as well: #189
