release_summary: release column contains a record when release_type is record

[duncandewhurst]

When release_type is 'record', the release_summary table contains a summary of the compiledRelease from the record. However, the release column contains the whole record, not just the compiled release. I would expect the release column to contain only the compiled release, as this is what is summarized in the other columns of the table.

If the release column can contain either a release or a record, it's harder to write queries that work for all release types.

We fixed a similar issue for embedded releases in #110 (comment)

This may be related to #43.
