Web search enters "Journal" field, which JabRef doesn't use

- JabRef version: 3.3dev
- Operating system and version: Win7
- Steps to reproduce:
  1. Enter any article title in "Web Search->Google Scholar" (e.g. "Alexanderian mean-variance risk-averse optimal control"
  2. Import
  3. Try to edit typos in journal title: not possible because journal is stored in field "journal", which JabRef does not display
