qgis#29895) This fix display of full circles coming from PostGIS.
There was a lack of a JSon array around rings of a polygon.
This issue is not present in 3.4
Also fixes an issue with gcc 5.5 of Ubuntu 16.04 that doesn't behave
properly with C++11 brace syntax with code from nlohmann/json.hpp.
The code compiles but the result is invalid: `json foo{ json::array{} }`
is serialized as [[]] instead of []. So use old-style constructor
instead: `json foo( json::array() )`
This PR is on top of qgis#30010
