Improve test output to include correct location (#2058) 
## Changes
- Add t.Helper() in testcli-related helpers, this ensures that output is
attributed correctly to test case and not to the helper.
- Modify testlcli.Run() to run process in foreground. This is needed for
t.Helper to work.
- Extend a few assertions with message to help attribute it to proper
helper where needed.

## Tests
Manually reviewed test output.

Before:

```
+ go test --timeout 3h -v -run TestDefaultPython/3.9 ./integration/bundle/

    workspace.go:26: aws
    golden.go:14: run args: [bundle, init, default-python, --config-file, config.json]
    runner.go:206: [databricks stderr]:
