* method #changed? also tracks changes of identites (fixes issue with email mapping)
* find ldap identity before initialize one

This outdated gem was the cause of those annoying MiniTest errors.

Also updates one use of `ensure_inclusion_of` which was deprecated in
favor of `validate_inclusion_of`.

This caused those random "true" outputs in the rspec output.

pry-rails has pry as a dependency and this lets us have all that pry
when we run `rails console` ❤

Abstracts away the lower-level implementation details from the
