ggplotly on geom_tile: unnecessary warning produced

[alanocallaghan]

When converting geom_tile with ggplotly, the warning 'heatmap' objects don't have these attributes: 'showlegend' is produced. I think this is just a mismatch in the internal API and should be an easy fix.

Seems to me that the issue arises here, where a value is assigned to it for all trace types. At least, if I comment this line out, the warning doesn't occur. https://github.com/ropensci/plotly/blob/e02a704d3743ef3dc59714af1b9fc6d3c248186e/R/ggplotly.R#L559

Also having this issue when converting geom_tilewith ggplotly:

EDIT:

resolved when I added linetype=1, and color="black" into my geom_hline of the tile plot.
