Currently, burn_in tags is generating tasks that allow for their compile steps to be bypassed and for them to retrieve their compiled code from a previous task. 

Bypass_compile in general has been brittle and has led to odd behavior at times. We disabled bypass_compile for most cases as part of https://jira.mongodb.org/browse/SERVER-50078. We should remove this step as well from burn_in_tags to make it consistent across the board.
