partial --select support for dbt < 1.5

[dlawin]

This PR allows --select to work with dbt versions < 1.5, but in a much simpler manner

Example on a version < 1.5:
--select <some_input>

The manifest is searched for <some_input> directly regardless of any dbt selectors like +, @ or multiple model names model_1 model_2. In the latter example, it would search the manifest for a single model named model_1 model_2

I've included a warning to help make this clear. See:

Can you mock this with these too to capture all the major manifest versions?

• 1.0
• 1.1
• 1.2
• 1.3

Really clever implementation! And the warning message nudges the user to upgrade dbt which is so great!

This failure seems unrelated but IF NOT EXISTS isn't being honored... race condition?

@dlawin Don't know about the test enough to provide a definite answer but doesn't look like it consistently impacts this PR, so we can ignore it here for now.
