[GH-133419] fix test_external_inspection race assert (#133422)

[tests] fix test_external_inspection race assert

either line could be where the inspection finds the foo()
function as after ready is sent, the process may not have made progress
onto the next line yet.  "solve" by putting the statements on the same
line.
