pickerInput labels (counts ) are too reactive

[gogonzo]

Counts of the filter are too reactive. Selecting values instantly trigger re render of the inputs. In case of the pickerInput one is not able to select multiple values because click instantly impacts the ui-input.

We need to find the non-invasive way to update the counts which won't retrigger reactive events. Also pickerInput selection should be applied only when picker is closed dreamRs/shinyWidgets#392

Per our discussion, the acceptance criteria is to decouple the filter counts/label from the input so we can separate the two activities.
