test: use common.hasIntl in tests related to ICU

We should use `common.hasIntl` in tests for test cases which are
related to ICU.
This way we can easily find the test cases that are Intl dependent.
Plus, it will be able to make the tests a little faster if we check
hasIntl first.

Also, this tweaks the log messages to unify the message.
