Evict project cache after project creation

Change I3724dfead introduced negative caching for in-memory project
cache. This means that non-existing project names are cached.
Pull-replication plugin checks if project exists, if not it creates
it, that's why after project creation pull-replication needs to reset
the project cache to remove newly created project name from
non-existing.
