### Description
`topos-redis` does not clean entries for failed and canceled calls.
modules are loaded in this order:
```
...
loadmodule "topos.so"
loadmodule "ndb_redis.so"
loadmodule "topos_redis.so"
# ----- ndb_redis params -----
modparam("ndb_redis", "server",
"name=srvC;addr=REDIS_HOST;port=REDIS_PORT;db=REDIS_DB_TOPOS")
# ----- topos params -----
modparam("topos", "storage", "redis")
modparam("topos_redis", "serverid", "srvC")
modparam("topos", "mask_callid", 0)
modparam("topos", "sanity_checks", 0)
modparam("topos", "branch_expire", 30)
modparam("topos", "dialog_expire", 14400)
modparam("topos", "clean_interval", 10)
...
```
When a call is answered the timer are working fine and the records are cleaned after
branch_expire timer.

When the call fails or it's canceled
```

after 30s
```
10.0.1.11:6379[9]> KEYS *
1) "d:z:atpsh-5d305fc4-51c3-1"
10.0.1.11:6379[9]> TTL "d:z:atpsh-5d305fc4-51c3-1"
(integer) 14319
```
The record `d:z:atpsh-5d305fc4-51c3-1` is not cleaned by the cancel or busy...it will
persist in the redis until it expires.
I upgraded my machine from 5.1.3 to 5.1.8 after finding this fix #1608 which I noticed in
the beginning.
