Deduplicate error from error causes

Changed

• Do not report error causes if the wrapper error has already been reported. This deduplicates errors and prevents the error wrapper and error cause to be reported separately, as long as the error wrapper is reported first.

  Ruby

  error_wrapper = nil
  error_cause = nil
  begin
    begin
      raise StandardError, "error cause"
    rescue => e
      error_cause = e
      raise Exception, "error wrapper"
    end
  rescue Exception => e
    error_wrapper = e
  end
   
  Appsignal.report_error(error_wrapper) # Reports error
  Appsignal.report_error(error_cause) # Doesn't report error

Fixed

• Fix an issue where the HTTP.rb gem integration would raise an error when a string containing non-ASCII characters is passed to the gem as the URL.
