fix(algolia): throw error if searchClient is missing (#1122)

* fix(algolia): throw error if searchClient is missing

It's a synchronous error, but as this is only for debugging, i don't think it makes a big difference how the error is thrown.

* move to invariant / clearer message

* no test

* not an option
