Access-lists and prefix-lists are disappearing after configuring `mpls ldp hello-ipv4-interval`.
Steps to reproduce:
```
# Start with a clean install
set interfaces ethernet eth0 address dhcp
set policy access-list 100 rule 1 source any
set policy access-list 100 rule 1 destination any
set policy access-list 100 rule 1 action permit
commit
run show ip access-list
# The access-list is present
run show ip prefix-list
# The access-list is present
set protocols mpls ldp discovery hello-ipv4-interval 1
commit
run show ip access-list
# The access-list is NOT present
run show ip prefix-list
# The access-list is NOT present
```
