[Test] Enable unit test suite: telemetry_sender.test.ts

[ananzh]

Description

All the unit tests related to unused telemetry are temporarily
skipped at forking. Unit tests of the disabled telemetry
functions should also be modified correspondingly. To build
a clean unit test, we decide to modify and enable all the
working unit tests. This PR modifies and enables
telemetry_sender.test.ts.
