fix issue 1076 by excluding wall post author from team members' array

Closes #1076 (closed)

What does this MR do?

exclude store wall post author from bell notification receivers

How confident are you it won't break things if deployed?

./scripts/test-rerun tests/api/StoreApiCest.php:canWriteStoreWallpostAndGetAllPosts --debug fails locally for me with 401 unauthorized

But as tests/api/StoreApiCest.php:canWriteStoreWallpostAndGetAllPosts passes in pipeline, it should not break anything.

I assume an additional test case is not needed as the test case :canWriteStoreWallpostAndGetAllPosts already exists.

How to test

Automated test: ./scripts/test tests/api/StoreApiCest.php:canWriteStoreWallpostAndGetAllPosts --debug

Manual test:

2. Login as foodsaver
3. Add a new store wall post
4. Assertion 1: You shouldn't receive a notification.
5. Logout and login as another foodsaver part of the store.
6. Assertion 2: This other foodsaver should have received a notification. (couldn't execute locally as login fails)
