Recently added "deprecated module" feature pints deprecation message every time
import statement is encountered. This results in excessive warning spam and
makes test coverage of deprecated modules problebatic.

Simple solution to make output more useful is to only print deprecation message
for the first deprecated import in the import chain. This is especially helpful
when module groups or packages get deprecated at once.
