Neo4j version 4 support

[Papillon6814]

Hello.
As written in README, bolt_sips does not compatible with neo4j version 4.

Neo4j versions used for test: 3.0, 3.1, 3.4, 3.5

mix test

So when I run mix test with version 4.4.12, one test does not work.
Can I work on this issue and send a PR? Because I'd like to use this library for my project. Thank you.

sure. Also specifying which "one test" doesn't work, would help clarifying the context better next time.
