[TASK] Quote identifier in messages with " instead of ' for ext:impexp

Log messages generally use double-quotes.  This patch fixes the
few stragglers that do not.

This also fixes an issue in PHP 8.1, where the defaults for
htmlspecialchars() have changed resulting in some test failures.
Standardizing the quotes makes the tests pass in all cases.
