Subject: T5817: Fix for show openvpn server
In some cases we can get error:
```
Traceback (most recent call last):
File "/usr/libexec/vyos/op_mode/show_openvpn.py", line 173, in <module>
data = get_status(args.mode, intf)
File "/usr/libexec/vyos/op_mode/show_openvpn.py", line 130, in get_status
client["tunnel"] = get_vpn_tunnel_address(client['remote'], interface)
File "/usr/libexec/vyos/op_mode/show_openvpn.py", line 66, in get_vpn_tunnel_address
tunnel_ip = lst[0].split(',')[0]
IndexError: list index out of range
```
(cherry picked from commit 58683a2444877bb989929625ad40a7d76259075d)
