Issue:
Person mit Leerzeichen am Anfang/Ende des Namens kann nicht gelöscht werden
**Describe the bug**

Eine Person mit Leerzeichen am Anfang oder Ende des Namens kann quasi nicht gelöscht werden.

Der Hinweis zum Löschen zeigt die Leerzeichen nicht an.  Dort steht:

> Bitte gebe zur Bestätigung "Hans Dampf" ein.

Obwohl der Name in der Datenbank `Hans ` `Dampf ` ist.

**To Reproduce**
Steps to reproduce the behavior:
1. Starte Anwendung mit Demo Daten
2. Füge in der Datenbank ein Leereichen z. B. an den Vornamen von "Hans Dampf"
3. Melde dich mit `office` an
4. Löscche die Person "Hans Dampf"

**Expected behavior**

Person wird gelöscht
