Inproceedings & inbook - booktitle replaced by series

Issue Summary

Hello,

It seems there is a problem with the booktitle and series fields when importing objects of type "@inproceeding" or "@inbook" from a bibtexfile. More precisely, if a "series" value is given in the bibtex file, then after the import, the series value appears as booktitle and series becomes null. If no "series" field is given, then the booktitle is well taken into account.

This is an example of what happens:
@inproceeding{test-09,
author = {Test, Test},
title = {TestTitle},
booktitle = {BookTestTitle},
series = {Meth Mol Med},
}
gets transformed into
@inproceeding{test-09,
author = {Test, Test},
title = {TestTitle},
booktitle = {Meth Mol Med}
}

Best regards,
Sorina
