Unhelpful error when email is incorrect in `galah_config()`

[daxkellie]

When an email is misspelled in galah_config(), the error message is very unhelpful

library(galah)
galah_config(email = "email-is-wrong@email.com",
             verbose = FALSE)
galah_call() |> 
    galah_identify("Anas superciliosa")|>              
    atlas_occurrences()

It would be nice to suggest to check whether the user's email is entered correctly when a code 500 error is returned

Just wanted to note that a Status code 500 error is generated when an email address is incorrectly entered with an @ symbol, but a Status code 400 error is triggered when an email address is entered incorrectly without an @ symbol.

Status code 400 is usually a more "catch-all" error, so for now I have only implemented a specific error message for a Status code 500 error. More investigating needs to be done whether the same solution could work for a 400 error.

This also explicitly solves issue #173
