test: fix a test crash by deleting test time later (envoyproxy#5145)

also pretty printing grpc test params while I'm in there because I dislike figuring out what test is failing via staring at Test/0 Test/1 Test/2 Test/3

Risk Level: Low (test only)
Testing: goes from 80% failure with flake-options on to 0% failure
Docs Changes: n/a
Release Notes: n/a
Fixes envoyproxy#5071
