In Rails 5 assigning a value which is not explicitly `true` or `false` to a boolean column transforms it to `true`.
In Rails 4 it transforms the value to `false` with the deprecation warning:

```
DEPRECATION WARNING: You attempted to assign a value which is not explicitly `true` or `false` ("nil") to a boolean column. Currently this value casts to `false`. This will change to match Ruby's semantics, and will cast to `true` in Rails 5. If you would like to maintain the current behavior, you should explicitly handle the values you would like cast to `false`.
```

This commit fixes the spec that expects to receive Rails 4 behavior.

Remove legacy storage path call

See merge request gitlab-org/gitlab-ce!18598

Since we only need the `can?` view helpers there, it's better to
include those in a separate controller.

If we inherit from `ApplicationController` we also need to deal with
authentication, that needs to be done in some, but not all doorkeeper controllers.

Storage shards should only be used, the exact paths are the

this instance the path is initialized, but never used so it could be
removed.
