## Context
Calendar tables are behind a featureFlag, they do not exist if the
feature flag is off which means we should not use them for the same
reason. I'm adding a check on the featureFlag before calling the
repository.
```
Error executing raw query for workspace 20202020-1c25-4d02-bf25-6aeccf7ea419: relation "workspace_1wgvd1injqtife6y4rvfbu3h5.calendarEventParticipant" does not exist
```
## Test
locally with and without featureflag
