Improve coverage for YMapControl and YMapHint

[ddubrava]

These components are not fully tested because the logic within the HintContainer and ControlContainer components is too complicated to be easily tested.

ControlContainer is relatively straightforward since there isn't much logic. The only issue is that we need to properly mock ymaps3.YMapGroupEntity<any>, as it is currently a function that is extended, and the overrides don't work for it.

HintContainer is insanely hard. E.g., it is impossible to catch throw new Error from synchronous code. And there is a lot of complicated API that needs to be mocked
