All deprecations except one are fixed

when I run all of the postgresql and sqlite3 tests.  When I fix this
last deprecation message, I will need to run the mysql and mysql2 tests.
The deprecation message that is left mentions this line:

Using `stub` from rspec-mocks' old `:should` syntax without explicitly
enabling the syntax is deprecated. Use the new `:expect` syntax or
explicitly enable `:should` instead. Called from
/Users/lrjiii/projects/schema_plus/spec/named_schemas_spec.rb:202:in
`(root)'.

or this line:

Using `any_instance` from rspec-mocks' old `:should` syntax without
explicitly enabling the syntax is deprecated. Use the new `:expect`
syntax or explicitly enable `:should` instead. Called from
/Users/lrjiii/projects/schema_plus/spec/foreign_key_spec.rb:35:in `block
(3 levels) in <top (required)>'.
