ee_Initialize() hides relevant error message

[MatthieuStigler]

runnign ee_Initialize(), I get error message: It looks like your EE credential has expired. Try running ee_Authenticate() again or clean your credentials ee_clean_user_credentials().

But looking it it carefully, this is not the problem. The real error message is:

Google Earth Engine API has not been used in project XXX before or it is disabled. Enable it by visiting https://console.developers.google.com/apis/api/earthengine.googleapis.com/overview?project=XXX then retry. If you enabled this API recently, wait a few minutes for the action to propagate to our systems and retry.

But this is hidden by the code below... it might be more informative to return the initial error message, rather than trying to guess the issue?

  ee_user <- tryCatch({
    rgee:::ee_check_root_folder()
  }, error=function(e) {
    stop(
      "It looks like your EE credential has expired. Try running ee_Authenticate() again",
      " or clean your credentials ee_clean_user_credentials()."
    )
  })
