Update geom_errorbarh to geom_errorbar

[luhann]

Hi,

Thanks for all the work you do on corncob.

I am busy attempting to implement TreeSummarizedExperiment support for corncob, in the process I noticed that tests were giving a warning due to the fact that plot.differentialTest was using geom_errorbarh which has been deprecated. This PR just updates the plot and all tests pass without issue now.

@luhann Thank you for noting this issue and submitting a PR! We really appreciate when people submit their own patches to issues they find in our software! However, I'm seeing failing R-CMD-checks (which I think is due to orientation = "x"). I replaced that with orientation = "y" in PR #189 , which resolves the errors, and checked that this doesn't affect the outputs. Could you confirm that this makes sense to you, or if it doesn't let me know why you used orientation = "x"?

Thanks!
Sarah

Yup, I just noticed that now, I had fixed the error after I noticed the vignettes not building but forgot to amend this commit with the fix. It's supposed to be orientation = "y", but if you've included it in #189 I can go ahead and close this.

Ok great, I'll close this and then merge PR #189. Thanks!
