Recent GDAL versions emit in the console a non critical warning when opening
world_map.gpkg at QGIS startup:
"Warning 1: Non-conformant content for record 1 in column update_time, 2019-08-15T21:28:22Z, successfully parsed"
The reason is that values in the update_time column in the layer_styles
column lack milliseconds information.
```
$ sqlite3 ../resources/data/world_map.gpkg "select update_time from layer_styles"
2019-08-15T21:28:22Z
2019-08-15T21:29:54Z
2019-08-15T21:30:31Z
2019-08-22T08:16:25Z
```
Fixed with:
```
$ sqlite3 ../resources/data/world_map.gpkg "update layer_styles set update_time = substr(update_time,0,length(update_time)) || '.000Z'"
$ sqlite3 ../resources/data/world_map.gpkg "select update_time from layer_styles"
2019-08-15T21:28:22.000Z
2019-08-15T21:29:54.000Z
2019-08-15T21:30:31.000Z
2019-08-22T08:16:25.000Z
```
