Fix replaced error handling in SQLite3Stmt::__construct

The error handling is replaced using zend_replace_error_handling(), but
when SQLITE3_CHECK_INITIALIZED() returns early, the old error handling
isn't restored.

In the past, SQLITE3_CHECK_INITIALIZED() threw a warning when the check
failed. This was replaced a few years ago with an error exception. So we
can fix the bug by just removing the replacing error handling as it
accomplishes nothing anymore.

Closes GH-11607.
