Branch names with slash don't work in active/standby

[shreddedbacon]

Describe the bug

When creating a project to use active/standby, if my production and standby production environments have / in the name, when triggering an active/standby it fails.

To Reproduce

Steps to reproduce the behavior:

1. Create a branch called prod/left and deploy it as productionEnvironment
2. Create a branch called prod/right and deploy it as standbyProductionEnvironment
3. Check the UI to see that both environments are production type
4. See in the UI that they are missing the active and standby labels
5. Attempt to trigger the active/standby switch directly with the API (as the UI button is not available)
6. Get an error

Expected behavior

Be able to trigger the switch without issue

Additional context

We do checks with environment by name, but due to #2322 it doesn't work correctly
