Fix: CONTAINS condition fails to match a value containing a backslash

[benno-truevault]

E.g.

Pdb::query("
CREATE TABLE IF NOT EXISTS ~dummy(
    id int NOT NULL AUTO_INCREMENT PRIMARY KEY,
    value varchar(255) NOT NULL
)", [], 'null');

try {
    Pdb::insert('dummy', ['id' => 1, 'value' => 'a\b']);
} catch (Exception) {
    // Assume record exists
}

function findRecord($conditions)
{
    $res = Pdb::find('dummy', $conditions)->all();
    echo json_encode($conditions, JSON_UNESCAPED_UNICODE | JSON_UNESCAPED_SLASHES), ' -> ';
    echo json_encode($res, JSON_PRETTY_PRINT | JSON_UNESCAPED_UNICODE | JSON_UNESCAPED_SLASHES), "\n";
}

findRecord(['value' => 'a\b']); // OK
findRecord([['value', 'CONTAINS', 'a\b']]); // Fails without this fix

No-brainer.

Earlier versions of sprout used str_replace and the replacement order matters in this case; the \ replacement has to be BEFORE the % replacement otherwise it breaks.

I'm not sure the replacement order for strtr but it might be worth investigating or testing this too.
