[16.0][IMP] mis_builder: preserve the filters when navigating back from drill-down

[IT-Ideas]

Prior to this commit the state of the searchModel was lost when navigating back from a drill-down.

This commit uses the globalState in order to store and restore the state of the searchModlel. The use of a SubEnv allows not having to pass props up to the widget, which would have required overriding the renderer, the compiler and field.
