meltano add extractor tap-google-analytics --include-related   causes a plugin install error.

### What is the current *bug* behavior?
When running `meltano add extractor tap-google-analytics --include-related` you get an error `File transform/dbt_project.yml could not be found. Run meltano add files dbt to set up a dbt project.` and at the end of the install process you get messages saying `Installed 5/6 plugins` & `Failed to install plugin(s)`

The dbt files do still get added under in the transform dir.

This is using python 3.8.5 & Meltano version 1.77.0


### What is the expected *correct* behavior?
No error should be displaying.



### Steps to reproduce
1. `meltano init new_project`
2. Inside the new project run `meltano add extractor tap-google-analytics --include-related`
3. You get the error `File transform/dbt_project.yml' could not be found. Run `meltano add files dbt` to set up a dbt project.` and the summary `Installed 5/6 plugins` & `Failed to install plugin(s)`
4. Look inside the transform dir, and you'll see the dbt files that apparently failed to install.
