Minor wording tweaks


* moved reference to schema_search_path earlier

* replace imperative voice directed at user “make sure to set” with description of what the gem does.

* use ‘activates its features whenever’ rather than ‘features only work if’, since the contrapositive of ‘only work if’ could be construed as ‘are broken if not’ :)
