dbQuery()'s two error paths for a prepare() or query() that returns false
logged $pdo->errorInfo. $pdo is not defined there, so PHP warned twice and
the message ended without the error. They also read dbLastError() from the
connection only after ZM\Error() had logged; with a database log target that
inserts into Logs through the same connection, which replaces its errorInfo,
so dbLastError() came back as "00000" instead of the error.
Read the error once, before logging, and use it for both. The query() path
also said "Error preparing" for a statement it ran directly.
These paths run when PDO's error mode doesn't throw; dbConnect() sets
ERRMODE_EXCEPTION, so normally the catch below handles the failure.
tests/php/test_database_error_paths.php drives both paths with
ERRMODE_SILENT and checks for no PHP warning and the real error text.
