[Test] broken Test.scrub_backtrace call

[vtjnash]

Saw this during a test run which failed (but then didn't print the actual failure):

  Got exception outside of a @test
  MethodError: no method matching scrub_backtrace(::Vector{Union{Ptr{Nothing}, Base.InterpreterIP}})
  
  Closest candidates are:
    scrub_backtrace(::Any, ::Any, ::Any)
     @ Test ~/julia/usr/share/julia/stdlib/v1.11/Test/src/Test.jl:89
  
  Stacktrace:
    [1] record(ts::Test.DefaultTestSet, t::Test.LogTestFailure)
      @ Test ~/julia/usr/share/julia/stdlib/v1.11/Test/src/logging.jl:152
    [2] macro expansion
      @ ~/.julia/packages/Colors/mIuXl/test/utilities.jl:23 [inlined]
