Check if requester is suspended before creating Zendesk ticket

[AgaDufrat]

It's not possible to create Zendesk ticket if a requester is suspended in Zendesk. The following error is raised:

  ZendeskAPI::Error::RecordInvalid:
  {"requester"=>[{"description"=>"Requester: <Name> is suspended."}]}
  (ZendeskAPI::Error::RecordInvalid)

We don't want to rescue ZendeskAPI::Error::RecordInvalid as this error is raised for other issue such as incorrect formatting.

Suspended users can be found https://govuk.zendesk.com/agent/user_filters

Testing

Tested in integration using Support app

attr = {
  :subject=>"Testing support api",
  "tags"=>["govt_form", "technical_fault", "fault_with_content_data", "govuk_platform_support", "slack_has_been_notified"],
"descreption"=>Testing. Assign to Aga Dufrat (2nd line — GOV.UK Alerts and Issues)"},
requester: { "email" => "<PPI-REDACTED>", "name" => "Some suspended user" }}
