Test Fix: Fix a test that can unintentionally fail in testAppName()

[Jake-WangZhi]

The app_name environment variable is not being set in the Blade instance before running the test. This leads to a null result from the environment, which does not match the randomly generated string (anyString).

Below is an example where it fails under NonDex on line 95

Failed tests:   testAppName(com.hellokaton.blade.BladeTest): expected:<9239184235> but was:<null>

Tests run: 1, Failures: 1, Errors: 0, Skipped: 0

To reproduce, run this at the root directory:

mvn -pl blade-core     edu.illinois:nondex-maven-plugin:2.1.7:nondex     -Dtest=com.hellokaton.blade.BladeTest#testAppName -DnondexRuns=10

(Note: We are running the test 10 times using -DnondexRuns=10, and it should fail each time.)

The log output can be found here for your reference:
mvn-nondex-1729136764.log

To resolve this, we should set the environment variable ENV_KEY_APP_NAME before running the test.

After applying the fix, the test should now pass with NonDex as expected:

Please let me know if this approach works for you. If not, I'm happy to discuss alternatives and am willing to spend more time to address the test in the way you'd prefer. Thank you!
