Comments are incorrectly flagged as hard coded references

[deanmorin]

Describe the bug

In some cases comments get flagged as hard coded references.

Steps to reproduce

In a comment, if a quoted string follows from or join it will be flagged as a hard coded reference.

-- from "a comment"
-- join "another comment"
-- from my_model
select
  1
from 
  {{ ref('my_model') }}

The first two comment lines (with the quoted strings) get flagged, the third line does not.

Expected results

No hard coded references found.

Actual results

Both "a comment" and "another comment" get flagged as hard coded references.

hey @deanmorin ! thanks for opening -- we can see if there's a straightforward way to skip commented lines. Can you help me understand why you might have from or join comments in your models?

@dave-connors-3 The actual comment that triggered this bug was describing what a particular CTE is for:

-- Find when the case first moves from "New" to any other status

We currently use commented-out SQL for our integration tests for hard-coded references, so if we were to make this change we'd need to rethink our tests for this package.
