Project not set for some resources

[zchadwickM2]

Describe the bug

There are a few resources that don't have the project argument set. They are:

• google_pubsub_topic.feed_output
• google_service_account.service_account
• google_project_iam_custom_role.enrichment_project_role

If you are not setting a provider block, ie

provider "google" {
  project = "example-project-id"
}

Then the module will fail. All other resources make use of the var.project_id.

Reproducing the Bug
Steps to reproduce the behavior:

1. Do not set a Google provider block with a project defined
2. Try to apply the code

Expected Behavior
Resources created even without a provider block with a project defined.

Screenshots

Output from a run before adding a provider block with a project:
