Collection contributors being saved with empty strings

[atomrab]

In Chrome, at least, the Editorial Note header in the collection view is large, indented, and not separated from the last citation field by a space, so that it appears to encroach on the "Contributors" data field (especially when the latter is blank). It should be left-justified, separated by a line break or paragraph space from the citation fields, and probably reduced in size (though I think it's fine if it stays a little larger than the other field names).

Update: I notice that this isn't a problem with local databases, since the edit collection/add period buttons separate the editorial note from the citation information. It's only a problem when viewing the canonical dataset, where those buttons do not appear.

The problem was that there are contributors being saved with empty strings. Still gotta address that.
