fix rest login error 500 for starkiller

[justsly]

try to login via the rest api always got me the following error:

HTTP/1.0 500
Content-Type: application/json
Content-Length: 54
Access-Control-Allow-Origin: *
Server: Werkzeug/1.0.0 Python/3.6.9
Date: Mon, 09 Mar 2020 15:48:02 GMT

{"error":"OperationalError('no such column: true',)"}

enabled must be check for '1' not 'true' to fix this issue and allow starkiller to work with the latest version of empire.

@justsly what version of Sqlite are you running? I think this might come down to whether your version of SQLite supports using boolean literals in queries, which came in SQLite 3.23

@Cx01N FWIW I think this is the only place that Empire uses this feature, so we can merge it to a 3.1.2

ah good point. I am running SQLite 3.22 which comes with ubuntu 18.04.4 LTS
