This is slightly linked #1741. 

In 
https://github.com/liquibase/liquibase/blob/10a0c509c59401e9351cf7d134b4bc671b5d500f/liquibase-core/src/main/java/liquibase/hub/HubUpdater.java#L364-L383

The currently held lock is released and then reacquired again. However, when using Liquibase programatically as a library the prompt is always disabled and therefore releasing and then acquiring the lock is entirely not needed.

Can I propose a change that will do

```
if (!Scope.getCurrentScope().getUI().getAllowPrompt()) {
    return;
}
```

This will solve the problem with the polluting of the logging with "Skipping auto-registration" since registering is anyways not possible when using it as a library.
