TT#64370 - Fix for topup voucher ajax error

* Ajax request failed when vouchers was
	   not set in ngcp_panel.conf under features
	   because it redirected to denied_page;
	   moved redirect to topup_voucher method
	   in Customer.pm because it doesn't work
	   on ajax requests

	 * Also hide the top up voucher button if
	   voucher option is not set under features
	   in ngcp_panel.conf
