Remove performance logs (#6709)

We have found the root cause of the issue:
- when using a datasource (including the cached ones), we are fetching
ObjectMetadataCollection from cache (700kB). Datasource usage is
happening any time we are using twentyORM, which is everywhere in the
jobs and in some resolvers (including the GetCurrentUser one). This is
leading to a high load on redis and leading to the performance issues we
are seeing.
- we actually don't need to fetch this objectMetadataCollection while
using a cached datasource, only when we instantiate a new one
