Optimize makeGetStatus (#11211)

* Optimize makeGetStatus

Because `ImmutableList.filter` always returns a new object and `createSelector`
memoizes based on object identity, the selector returned by `makeGetStatus`
would *always* execute.

To avoid that, we wrap `getFilters` into a new memoizer that memoizes based on
deep equality, thus returning the same object as long as the filters haven't
changed, allowing the memoization of `makeGetStatus` to work.

Furthermore, we memoize the compiled regexs instead of recomputing them each
time the selector is called.

* Fix memoized result being cleared too often

* Make notifications use memoized getFiltersRegex
