fix: remove task dependency that breaks mise --env context

The depends directive on test:integration:without_multitenant caused
issues when called via `mise --env tls run` because mise doesn't
properly pass the environment context to dependency tasks.

For standalone use, run test:integration:setup:tls manually first.
