Remove noise in specs

What does this Merge Request do and why?

⚠ This MR needs !2007 (merged) merged.

Before

$ make rspec
RSpec: ........................<newline here>

After

$ make rspec
RSpec: ....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................
