[FIX] core: make accessing fields from __str__ possible

Because CacheMiss calls str() on the record it's given, it's not
possible to override __str__ and get field values: on the first cache
miss (= the first field access) we're going to blow the stack:

* any random field is accessed
* and faults
* which creates a CacheMiss
* which stringifies the record
* which accesses a field
* which faults
* which creates a CacheMiss
* etc...

Fix:

* move the basic Model's stringification to repr(), which is
  implicitly called on str() if no __str__ is specified, for historical
  reasons we were doing the opposite
* use repr() when initialising CacheMiss
