Fix summary command when internal terraform config doesn't exist (#1242)

Check if `bundle.tf.json` doesn't exist and create it before executing
`terraform init` (inside `terraform.Load`)

Fixes a problem when during `terraform.Load` it fails with: 
```
Error: Failed to load plugin schemas

Error while loading schemas for plugin components: Failed to obtain provider
schema: Could not load the schema for provider
registry.terraform.io/databricks/databricks: failed to instantiate provider
"registry.terraform.io/databricks/databricks" to obtain schema: unavailable
provider "registry.terraform.io/databricks/databricks"..
```
