Correction: Swinburne Harvard should ignore `publisher` field in journal citations

[wale]

As it stands, the CSL file for Swinburne Harvard sets the publisher macro regardless of citation type: https://github.com/citation-style-language/styles/blob/b2be5aeeee7f00fd2032ac1daad995bbe95398cf/harvard-swinburne-university-of-technology.csl#L99-L104

This is in opposition to the specification, where books need to have the publisher detailed in the citation, but not journals, newspaper articles or magazines.

Current example:

Campbell, JL & Pedersen, OK 2007, ‘The Varieties of Capitalism and Hybrid Success: Denmark in the Global Economy’, Comparative Political Studies, vol. 40, no. 3, SAGE Publications Inc, pp. 307–332.

What it should contain:

Campbell, JL & Pedersen, OK 2007, ‘The Varieties of Capitalism and Hybrid Success: Denmark in the Global Economy’, Comparative Political Studies, vol. 40, no. 3, pp. 307–332.
