[BUG] Fix missing y-axis for TSVB (#2079)

Issue:
#1873

This was happening because of a prop useDefaultGroupDomain. This prop was introduced into the elastic charts to allow clustering for the multiple series which will share a common Y domain i.e for example the stacked and non- stacked bars will have the same Y common domain/axis. As per the elastic/charts whenever the useDefaultGroupDomain is set to true, it will force to group the series/visualiations groupId's to a default group domain. But, TSVB is not a shared Y domain. So the prop is unneeded.

Further insight:

From the code:
```
const groupId = hasSeparateAxis || isStackedWithinSeries ? seriesGroup.id : mainAxisGroupId;
```
where
```
const mainAxisGroupId = yAxisIdGenerator('main_group');
```
... which indicates that the global default `groupId` is not used by TSVB. Hence, TSVB should have not been using `useDefaultGroupDomain` ever.
