Fixed the loop for authorized keys. While I read previously that the
Ansible module can take keys in the array format:
```yaml
key:
- key1
- key2
- ...
```
This seems to not be the case.
Instead, we now do a 'sub-loop' through all the existing authorized_keys
entries in the data structure, running the task once for each key.
This also means we can simplify the 'when' condition to only check the
data structure itself exists, not the key since we only loop once for
each existing key anyway.

One drawback:
we can now _not_ change the key setting in the module to be exclusive
(`exclusive: true` for `authorized_keys` module). As described in the
documentation, if there are more than one key for a user, this would
lead to the following keys overwriting the first key.
Currently do not know how to fix this, but we are not supplying
exclusive keys so it is fine for the moment.
