rib: normalises the name and normalise even more the RIB and IBAN

We got ASP errors because:

- the INTITDEST (i.e Rib#name) had `\t` in them – they were input with
tabulation as space, which is perfectly legitimate to me. Clean up the
value to adress that.

- the BIC length was over 11, which is because of space around
them (we took care of that) but also sometimes in the middle of the
value. Take care of that too now, and refactor a bit to reduce duplication.

NOTE: bonus points: we can use something like:

```ruby
Rib.find_each do |rib|
  rib.normalize_attribute(:iban)
  rib.normalize_attribute(:bic)
  rib.normalize_attribute(:name)

  rib.save! # this will not trigger an update query if there are no changes^
```

Closes #677.
