errounous semicolon after single-line location block

[Mic92]

Reported in NixOS/nixpkgs#57979 (comment):

The following configuration:

location /example { allow 192.168.0.0/16; deny all; }

results in

  location /example {
    allow 192.168.0.0/16;
    deny all;
  }
  ;

the trailing ; will produce an error message in nginx like this:

апр 08 14:55:45 web.elven.pw systemd[1]: Starting Nginx Web Server...
апр 08 14:55:45 web.elven.pw pnzhwc1q1is8vbdkg34ksicqq9jh5chc-unit-script-nginx-pre-start[2430]: nginx: [emerg] unexpected ";" in /nix/store/glvppaxv9gqg9vj179ph9rmj8yg41d72-nginx.conf:151

The nginx version is 1.14.2.

Here is a workaround NixOS/nixpkgs#59181
However I would very much prefer a fix in nginx-config-formatter instead.
