Fix: Website commands now use lazy lookup

Supporting `pre.erb` means that any lookups need to happen at the last possible moment. Websites have a name lookup feature similar to background tasks. Background tasks adopted a lazy lookup model in `4.1.2`.

Ensuring these are all covered under test:

- `website.screenshot` is covered:

```
  1) Error:
SystemsCliTest#test_screenshots_dir:
  2) Error:
IntegrationWebsiteTest#test_screenshot_command:
```

- `website.visit` is covered

```
  1) Error:
SystemsCliTest#test_screenshots_dir:
  2) Error:
IntegrationWebsiteTest#test_screenshot_command:
```

- `website.navigate` is not covered. Adding a call to the integration test so it's at last exercised

 ## HEAD
 
+- Fix: Website commands such as `:::>> website.visit(...)` now use lazy lookup (like Background tasks since 4.1.2). This allows `pre.erb` to be used with these commands ()
+
 ## 4.1.2
 
 - Fix: Background task name lookup is now lazy, this fixes a bug when using `:::>- pre.erb background.start(...)` (https://github.com/zombocom/rundoc/pull/95)
