Empty i18n messages if .angular dir exists

Is this a regression?

In the previous angular versions there was no that directory.

Description

I have created a simple repo that demonstrates the issue. When you first run ng extract-i18n everything is fine, but once the .angular directory is created it stops working as expected - the generated file is empty.
