print testset name while waiting for results?

[ericphanson]

Taking the example from the docs:

julia> retest("greet", verbose=2) # run only tests related to `greet()`
                         Pass
MyPackage:
  greet              |      1

If greet was super slow, you'd get

julia> retest("greet", verbose=2) # run only tests related to `greet()`
                         Pass
MyPackage:

while waiting for greet to finish running. I think it would be nice if instead it showed

julia> retest("greet", verbose=2) # run only tests related to `greet()`
                         Pass
MyPackage:
  greet              |      

so you knew which test was running. (Especially for when you do shuffle=true!). I.e. it could print the testset name while waiting to print the pass.

So this is kinda already implemented, controlled by the spin keyword argument of retest, but this requires typically that Threads.nthreads() > 1. When spin is not active, we could definitely print the test name without the spinner.
