MockStore: props are dropped when MockStore is passing selectors to actual Store

[alex-okrushko]

Uncovered during the merge: selectors with Props were getting undefined instead of the prop values.
This is happening because MockStore wasn't taking Props in the select implementation, so it's not passing anything down to the Store as well.

platform/modules/store/testing/src/mock_store.ts

Line 98 in 4a5153c

select(selector: any) {

I would be willing to submit a PR to fix this issue
