The PRACK is handled correctly when TOPOS is disabled.
#### Reproduction

#### Configuration
```
modparam("ndb_redis", "server","name=srv1;addr=192.168.10.123;port=6379;db=1")
modparam("topos", "storage", "redis")
modparam("topos_redis", "serverid", "srv1")
modparam("topos", "sanity_checks", 1)
modparam("topos", "branch_expire", 180)
modparam("topos", "dialog_expire", 36000)
modparam("topos", "clean_interval", 30)
modparam("topos", "contact_mode", 1)
modparam("topos", "rr_update", 1)
modparam("topos", "event_mode", 2)
modparam("topos", "methods_nocontact","BYE,CANCEL")
```
