pkg: newlog: make a small improvement

This commit makes a small improvement in newlogd.go:

- Agregate two ifs into one: getAppStatsMap() must be called only if
  appuuid is not null
- Remove redundant attribution: getAppStatsMap() already attributes the
  found item to the map ("appStatsMap[appuuid] = appM") inside the
  function
