API: missing abstract in submissions

[henriquejsfj]

Describe the bug
This bug is related with the REST API only.

According to docs, inside the array of publications from an article or issue should have the abstract.
However, the abstract is not being returned on /issues nor on /submissions. I was able to see the abstract by accessing the /publications endpoint.

I tried even with admin's Token, without success.
(No errors reported from OJS server back-end)

What application are you using?
OJS 3.4.0.8

@ewhanson, can you take a look?

I suspect that this is a documentation error; off the top of my head, the abstract should be on the /publications endpoint, not submissions. If it were provided on /submissions, it would only be a read-only convenience.
