Fix Date metricid cache consistency under concurrent use (#6534) 
### Describe Your Changes

Fix Date metricid cache consistency under concurrent use.
When one goroutine calls Has() and does not find the cache entry in the
immutable map it will acquire a lock and check the mutable map. And it
is possible that before that lock is acquired, the entry is moved from
the mutable map to the immutable map by another goroutine causing a
cache miss.

The fix is to check the immutable map again once the lock is acquired. 

### Checklist

The following checks are **mandatory**:
