Issue Description

There seems to be an issue around the appsetting -SCM_DO_BUILD_DURING_DEPLOYMENT 0 in the AzureFunctionApp@2 task.

I made certain my template was configured properly, I ruled out any "technical issues" regarding values used for the variables, etc. Adding an additional setting breaks the deployment when combined with "SCM_DO_BUILD_DURING_DEPLOYMENT"

GOOD

-PartnerConfigSettings $(PartnerConfigSettings)
