Fix: 'internal server error' when pushing the same commit twice
On the second push of the same commit to 'refs/for/<branch name>', Gerrit
returns 'no new changes'.
However if the user pushes to 'refs/changes/<change id>', Gerrit returns
'internal server error'.
The reason is ReceiveCommits$ReplaceRequest.validate() checks
'squash commits first' ahead of 'commit already exists' and
ReceiveCommits.insertChangesAndPatchSets() replaces the error message
with 'internal server error' without any checking.
