Update Log model to not overwrite time

[JWardee]

In src/Models/Logs.php line 199-200 we move time to timestamp, but this has lead to it needing to be writen back in src/Loggers/LogHelper.php line 70 to allow for hooks to work correctly. Ideally we'd just have time always contain the timestamp and have the human readable time in a different property (eg human_time) which'll allow us to remove the hacky rewriting of the property
