test: Add missing logging info for each test

Add self.log.info(...) calls at the beginning of each test
in GetBlocksActivityTest.

This improves readability and provides debugging information
by logging the purpose of each test upon its correct
execution.

This is in preparation for the next commit, which adds a new test
with log info, and it would look inconsistent without this commit.
