[4.4] Fix Sample data installation, fix finder helper addContentType null value

[Fedik]

Pull Request for Issue # .

Summary of Changes

Helper::addContentType() allows null for mime, however $db->quote() does not.
Same as #43051 but for 4.4

Testing Instructions

Use PHP 8+, set error reaporting to Maximum.
Set DB driver to use MySQL PDO
On clean installation, try install "Blog Sample Data"

Run following code (example in index.php of the template):

$name = uniqid(); // Imitating a new content type name, can be any string
var_dump(Joomla\Component\Finder\Administrator\Indexer\Helper::addContentType($name));

Actual result BEFORE applying this Pull Request

PHP warning Deprecated: PDO::quote(): Passing null to parameter 1 ($string) of type string is deprecated

Expected result AFTER applying this Pull Request

No warning

I have updated test instruction,
old one was more for 5.x.

Don't got the error in Joomla 4.4.7-dev, Mamp 7, PHP 8.3.8, Mac 14.5:

[Fedik]

Error reaporting should be set to Maximum. To be able to see messages about deprections.

[ghost]

Error reporting was set to Maximum.

[Fedik]

Something is hidding the PHP message then. Can also try like:

error_reporting(E_ALL);
ini_set('display_errors', 'On');
$name = uniqid(); // Imitating a new content type name, can be any string
var_dump(Joomla\Component\Finder\Administrator\Indexer\Helper::addContentType($name));

I cannot create the error either.

All that happens is that an int is displayed which increases on each page load

[Fedik]

I have no idea then. I can clearly see it on my PHP 8.1

[Fedik]

Ah, wait. I found, please use MySQL PDO, not MySQLi.
I have update the issue description.
