Deleting multiple ephemeral instances only removes the first

[simondeziel]

How to reproduce:

$ lxc launch --ephemeral ubuntu:22.04 foo1
Creating foo1
Starting foo1
$ lxc launch --ephemeral ubuntu:22.04 foo2
Creating foo2
Starting foo2
$ lxc list foo
+------+---------+---------------------+-----------------------------------------------+-----------------------+-----------+
| NAME |  STATE  |        IPV4         |                     IPV6                      |         TYPE          | SNAPSHOTS |
+------+---------+---------------------+-----------------------------------------------+-----------------------+-----------+
| foo1 | RUNNING | 10.76.66.80 (eth0)  | fd42:b2a9:e8fd:1156:216:3eff:fe54:e684 (eth0) | CONTAINER (EPHEMERAL) | 1         |
+------+---------+---------------------+-----------------------------------------------+-----------------------+-----------+
| foo2 | RUNNING | 10.76.66.125 (eth0) | fd42:b2a9:e8fd:1156:216:3eff:feb7:cb8d (eth0) | CONTAINER (EPHEMERAL) | 1         |
+------+---------+---------------------+-----------------------------------------------+-----------------------+-----------+

$ lxc delete -f foo1 foo2
$ echo $?
0

$ lxc list foo
+------+---------+---------------------+-----------------------------------------------+-----------------------+-----------+
| NAME |  STATE  |        IPV4         |                     IPV6                      |         TYPE          | SNAPSHOTS |
