fix: allow TLS with remote docker when using public CA

Browse Source 
This provides a small fix that allows you to define docker hosts that
you can connect with in three different ways:

1. Mutual TLS, docker host uses non-standard CA
2. Mutual TLS, docker host uses standard CA
3. No Authentication, docker host uses non-standard CA
4. No authentication, docker host uses standard CA

In the previous implementation only condition 1 and 4 were allowed. This
makes condition 2 and 3 possible. The logic is a little messy, but it
works.
