🐛 Keep order of elements in replace functions

[Friedinger]

Problem:

replaceAll adds new content at end of parent element, not at the expected position

Example:

Code executed: $content->replaceAll("user-username", $user->getUsername());
Template: <p>Passwort des Accounts <user-username /> ändern:</p>
Actual Output: <p>Passwort des Accounts ändern:admin</p>
Expected Output: <p>Passwort des Accounts admin ändern:</p>

Was already fixed in Commit 0a2a430, problem only occured in other project with old version of FileRouter
