Error: Column `Ratings` must be length 1, not 0

[robinpellegrims]

For some reason, omdbapi sometimes returns an empty value for the Ratings field (probably a bug on their side). But when this happens, this library's functions throw the following error:

Error: Column 'Ratings' must be length 1, not 0

Can be handled more gracefully? It is still interesting to get all the other fields as a result.

Example call: find_by_id('tt6911608', type='movie', include_tomatoes = TRUE)

I'm guessing the issue is in using dplyr::as_data_frame on the following line: https://github.com/hrbrmstr/omdbapi/blob/593775319bc8ce1ad004e3a20a73369fd98247b2/R/title_or_id.R#L89
