Fix project creation replication integration test

When a new project is created, the replication event is triggering
a remote 'git init --bare' using the adminUrl and the re-scheduled after
the retry period.

Make sure that the second retried replication event associated with the creation
of new projects is getting scheduled and executed properly.
