Generated config file is invalid when the AllowedIPs field is left blank

[t-aleksander]

If the location doesn't have any allowedips set (which is optional), its generated config file (downloadable during the enrollment or from the dashboard) will be impossible to parse by the wg-quick command or the wireguard GUI client.

[#] ip link add lokacja type wireguard
[#] wg setconf lokacja /dev/fd/63
Line unrecognized: `AllowedIPs='
Configuration parsing error
[#] ip link delete dev lokacja

Currently the AllowedIPs line looks like this in such scenario:

AllowedIPs =

Instead, if there are no allowedips specified, it should be empty altogether. The issue doesn't occur when importing the config via the defguard client menu.
