dbt clean regression

[tmastny]

Describe the bug

In dbt 0.16.1 dbt clean fails without a profile:

(dbt) dbt$ dbt --version
installed version: 0.16.1
   latest version: 0.17.0

Your version of dbt is out of date! You can find instructions for upgrading here:
https://docs.getdbt.com/docs/installation
(dbt) dbt$ dbt clean
Running with dbt=0.16.1
Encountered an error while reading the project:
  ERROR: Runtime Error
  Could not find profile named 'profile'
Encountered an error:
Runtime Error
  Could not run dbt

In dbt 0.15.1, dbt clean works.

(dbt) dbt$ dbt --version
installed version: 0.15.1
   latest version: 0.17.0

Your version of dbt is out of date! You can find instructions for upgrading here:
https://docs.getdbt.com/docs/installation
(dbt) dbt$ dbt clean
Running with dbt=0.15.1
Checking target/*
 Cleaned target/*
Finished cleaning all paths.

Steps To Reproduce

Delete any profile found in ~/.dbt/profile.yml.

Install 0.16.1:

pip install dbt==0.16.1

Navigate to dbt project:

dbt clean

Repeat for 0.15.1 to confirm regression.

Expected behavior

I expected dbt clean to work without a profile. This broke some of our automated jobs when we tried to upgrade.

System information

Which database are you using dbt with?

• postgres
• redshift
• bigquery
• snowflake
• other (specify: ____________)

The output of dbt --version:
Multiple versions. See above.

The operating system you're using:
macOS 10.14.6

The output of python --version:

(dbt) dbt$ python --version
Python 3.7.3

Additional context

Most people probably don't run dbt clean without a profile, but it was causing us confusion, so wanted to document it as a breaking change at least.

I also tested this with 0.17.0: same error as 0.16.1.

(dbt) dbt$ dbt --version
installed version: 0.17.0
   latest version: 0.17.0

Up to date!

Plugins:
  - bigquery: 0.17.0
  - snowflake: 0.17.0
  - redshift: 0.17.0

Thanks for pointing this out, @tmastny. You're right that it's a regression.

We removed the profile requirement for dbt deps in 0.16.1 (#2231), but it seems like we didn't fix it for dbt clean.
