TeamCity: Make service sweepers run before project sweepers, assert that in a test

[SarahFrench]

Closes hashicorp/terraform-provider-google#17556

This PR makes sure project sweepers enter the build queue after service sweepers do, effectively ensuring that service sweepers run first and the project sweeper build will wait for them to complete before leaving the queue itself.

The desired consequence of this is that all resources that put liens on projects will be removed, so the project sweeper will experience fewer blocks on deleting projects due to liens.

This is gross and I need to figure out if there's a better way to do this
