Event invoices are not fetched properly in /review route

[shreyanshdwivedi]

Describe the bug

Currently, we use filter to get a particular event invoice. Also we are not redirecting request from review to paid even if it is paid

let filterOptions = [
      {
        name : 'identifier',
        op   : 'eq',
        val  : params.invoice_identifier
      }
    ];

Expected behaviour

We can use proper GET API to fetch invoice
