snp without class fails with ncbi_snp_query()

[jooolia]

Please do not submit bug reports for issues with the OpenSNP or NCBI’s dbSNP server itself. rsnps is only an API client, it does not have control over the server hosting the data.

Describe the bug
A clear and concise description of what the bug is.

Code to reproduce
ncbi_snp_query("rs539690682")

Expected behaviour
Should give NCBI information about snp. Instead gives error:

Error in if (Class %in% c("snv", "snp", "delins")) { :
argument is of length zero

OS and R versions (please complete the following information):

• OS: [e.g., Windows10, macOS, Linux] macOS
