Fix blueprint name conflict

The name conflict would result in the following error when some alice tests ran before the MSC2716 tests.
```
=== RUN   TestBackfillingHistory
    msc2716_test.go:54: Deploy times: 18.499364ms blueprints, 1.581230486s containers
    msc2716_test.go:60: Deployment.Client - HS name 'hs1' - user ID '@the-bridge-user:hs1' not found
```
