peek_cjsg() returns error when there are 0 results #23

Closed jtrecenti closed 6 years ago

Example

n_pags <- esaj::peek_cjsg(query = "", subjects = "14")  
#> There are 169 pages to download
#> This should take around 1.4 minutes
n_pags                                                  
#> [1] 167

n_pags <- esaj::peek_cjsg(query = "", subjects = "5944")
#> Error in ceiling(.): non-numeric argument to mathematical function

I think it should throw a message and return 0L

Also the result is always numeric. it should be an integer.
