systemd-homed: pressing the Enter key when the password field is empty causes an endless loading cycle.

[linux-universe]

Steps to reproduce:

1. log out or lock out
2. make sure there‘s nothing in the password field
3. press enter

EDIT:

• looks like this is only a issue on systemd-homed accounts

i tried to get some logs:

# i have two users. non-systemd-homed-user where i logged in a tty to get the logs and "test" for the homed user
# this is a vm test setup
