parseConnectEndStream repeats the default status phrase in the message
body, so the trailer reads "resource_exhausted: resource exhausted".
Using a global strip removes both occurrences, so the leftover
"exhausted" no longer trips the generic quota branch and reintroduces
the 30-minute credential block for an otherwise bare status.
Fixes#7032
