[BUG] Fix record relation optimistic mutation (#9881)

# Introduction
It seems like optimistic caching isn't working as expected for any
record relation mutation, CREATE UPDATE DELETE.
It should not have an impact on the destroy

We included a new `computeOptimisticRecordInput` that will calculate if
a relation is added or detach.

Updated the `triggerCreateRecordsOptimisticEffect` signature we should
have a look to each of its call to determine if it should be checking
cache or not
