Run Spinach and RSpec separately in parallel on Semaphore
Created by: cirosantilli
Before, if Spinach failed RSpec would also run since they were run in parallel.
Not both run in series, so:
- if Spinach fails (and if fails a lot because of random failures) we don't see the RSpec, so an unrelated failure on Spinach can hide real RSpec failures
- it takes twice as long
Can't we back to how it was before?
