CRM-17789 - api/v3/ReportTemplate - Indicate type correctly

The return value of `civicrm_api*()` is generally `array`, but when used
with `getvalue` it can be scalar (specifically, `string` in this case).
This produces a type-warning in phan because it cannot tell that the true
return type is `string`.
