v1.11.1 dbt_shopify

PR #187 and PR #190 include the following updates:

Bug Fix

• dbt compile fails on a new schema because the get_metafields macro queries stg_shopify__metafield before it exists. The macro now queries metafield keys only during dbt run and dbt build, which fixes compile for all *_metafields models.
• dbt v2 strict compile (--static-analysis strict) fails on DuckDB because shopify__calendar compares a timestamp to a date. shopify__calendar.date_day is now a date on every warehouse, and the shopify_lookback macro now returns a date. This fixes strict compile for shopify__calendar, the *__daily_shop models and the *__customer_cohorts and *__customer_email_cohorts models. Their output values don't change.
