Remove useless message from tsl_cagg_try_repair

The PR #3899 introduced a new function named `tsl_cagg_try_repair` to
try to fix buggy Continuous Aggregates that lead to segfault on a select
query. It added an INFO message when skipping the check for Continuous
Aggregate that don't have partials and it's annoying during the
upgrade/downgrade the extension specially if you have many Continuous
Aggregate.

Remove this message because it's completely useless.
