Title: Revert "truncate debug.log on each test run"

This reverts commit 98043c689f945cabffc043f4bdc80ab2a7edc763. See #7994 .

Because if every time `debug.log` is truncated, developers have no way to see the previous ActiveRecord unit test results.

`debug.log` file can be easily reduced by executing `$ touch /dev/null > debug.log` periodically.
