Subject: fix(tazblog): Ensure build works with MonadFail changes

This updates some old code that makes assumptions via pattern matching
to instead make assumptions via a Prelude function.

This is known to be safe as it has been running fine for almost a
decade now, but the recent MonadFail changes broke the build.
