chore: phpunit migrate configuration

[vishwarajanand]

Script ran to migrate configurations is below

#!/bin/bash

php_samples_path="$HOME/github/php-docs-samples/"
products=(
        "testing"
        "bigquery"
        "bigtable"
        "spanner"
        "firestore"
        "datastore"
        "storage"
        "pubsub"
    )
for phpunit_config in $(find * -name 'phpunit.xml*' -not -path '*vendor/*' );
do
    dir=$(dirname $phpunit_config)
    # echo -e "\n Checking => $dir\n " "${products[@]}"
    # echo "${dir%/%%/*}"
    if [[ "${products[@]}" != *"${dir%%/*}"* ]]; then
        # echo -e "\n Skiping => $dir\n"
        continue
    fi
    echo -e "\n RUNNING for => $phpunit_config\n"
    $php_samples_path/testing/vendor/bin/phpunit  -c $phpunit_config --migrate-configuration && git add "${phpunit_config}"
done

Log file showing no failure

Context: #1863 was giving failures when the phpunit configs were run. Hence, limiting the scope so that this work can be brought to concluson.

The failing test (log) runs fine on my local:

pubsub/app % ../../testing/vendor/bin/phpunit -c phpunit.xml.dist
PHPUnit 9.6.10 by Sebastian Bergmann and contributors.

Warning:       XDEBUG_MODE=coverage or xdebug.mode=coverage has to be set

...                                                                 3 / 3 (100%)

Time: 00:04.422, Memory: 12.00 MB

OK (3 tests, 4 assertions)
pubsub/app %

So, it seems to be missing a subscription name which is hardcoded in pubsub/app/index.php and it already exists. I am re-running the tests, if it fails I will revert the pubsub/app/* changes.
