Prevent querying of db when compiling

This is a:

• [ x ] bug fix PR with no breaking changes
• new functionality
• a breaking change

Description & motivation

I keep seeing these weird fake test failures when running dbt compile. Based on this conversion dbt-labs/dbt-core#4575 (comment) it seems to be because dbt compile sets execute to true during one of its phases. This makes it so that db parsing is also stopped when compiling
