Fix an edge case when loading replay start state by slot (#7313)
* Ensure start state is the parent of the first block
* Regression test
* Merge branch 'master' into state-by-slot-state-state
* Add back the line
* Merge branch 'state-by-slot-state-state' of github.com:prysmaticlabs/prysm into state-by-slot-state-state
* Add a test for lower slot block condition
