Steps to reproduce

• Create a custom post type and specify that it does not support author (similar to Page).
• Create a new post of that post type.
• View that post on the front end.
• The author is shown under the title, even though the post type does not support author.

@ianbelanger - The patch, https://core.trac.wordpress.org/attachment/ticket/48803/48803.diff, should fix the issue.

The patch does fix the issue, however while testing I found that the author bio box also shows on CPT's that don't support authors. I think that we should probably fix this issue as well.
