initialize task fails silently

Hello

Gradle 6.7

### Actual Behavior:
When I run the following build script :

```
- $GRADLE_HOME/bin/gradle :initialize
- $GRADLE_HOME/bin/gradle :deploy
```

The build continue even when the initialize step fails

```
> Task :shadowJar UP-TO-DATE
Initializing the backend...
Error refreshing state: AccessDenied: Access Denied
status code: 403, request id: EEEEEEE7C7C228D1, host id: J========================================================================
> Task :initialize
Error: Error loading state: AccessDenied: Access Denied
status code: 403, request id: EEEEEEE7C7C228D1, host id: J========================================================================
> Task :deploy
```

### Expected Behavior:
The gradle task :deploy should not be executed when the :initialize task fails

Reproduce the issue with Gradle 6.7 using the shown :initialize and :deploy task commands, including the AccessDenied failure. Inspect how the initialize task reports errors and how deploy is triggered; done means deploy is not executed when initialize fails.
