Title: Fix worker growth to actually check est. memory

I believe that ```:cycle``` was always intended to grow workers by calling
:under_memory if the estimate of how much memory we would use by adding
a worker is safe given constraints of PumaAutoTune.ram. The existing
```if``` check in :cycle did not actually check anything I don't
believe.
