[FiltersPanel]: fix unnecessary api calls on each picker filter body opening

## Actual result

Filter panel picker type filters with async/lazy datasource produce unnecessary api calls on each body open, not only on the first one.

## Expected result

Filter should load data only on first opening, then already loaded data should be used.

Note:
It behaves this way because FilterPickerBody create datasource.view inside and then body remounting each time on body open which leads to recreation view and new data load

## Environment
* UUI version: 5.10.1
