When a new MongoClient is created with auto_encryption_options that include a valid local schema, users get a spurious message: "WARNING local schema used but does not have encryption specifiers". Subsequent insert & find operations work as expected (automatic encryption is in fact occurring).

Reproducible test case from (PYTHON-1983): https://jira.mongodb.org/secure/attachment/231133/hello_fle_python.py

$ python hello_fle_python.py
1.0.0-beta4
WARNING local schema used but does not have encryption specifiers
WARNING local schema used but does not have encryption specifiers
WARNING local schema used but does not have encryption specifiers
Encrypted insert & find succeeded.

This warning should only display when a local schema was specified but lacked any encrypt properties in the json schema.
