Dev mode persists checks (docker)

#### Overview of the Issue

We are using dev mode with a single consul node for our local development stack. With the new release we see that even after restarting the consul docker instance the checks persist while it says in the documentation that dev mode does not persist anything.

#### Reproduction Steps

Steps to reproduce this issue, eg:

1. Run a consul docker instance
1. Register a check
1. Restart docker instance, see that the check is still there

### Operating system and Environment details

Windows 10, Docker Instance
