New "empty" entries are not removed

[Trekky12]

Describe the bug
When a new password entry is generated from the floating button the entry and no text is inserted the "empty" entry is still in the password list when the detail screen is closed.

To Reproduce
Steps to reproduce the behavior:

1. Click on +
2. Go back to password list
3. See "empty" password entry with the label "(kein Titel)"
4. See the "save" icon despite no changes were made and no warning is shown

Expected behavior
The "empty" entry should not be removed.

Additional context
Apparently when adding a new password entry the entry in die kdbx file is always generated. This entry should be removed when no input is made.

Maybe this is related to (and can be fixed with) #91
