Inconsistency between space/environments locales and default locale

[HQ063]

There is some inconsistency regarding locales and default locale on space and environment. The locales are defined in a specific environment, but the default locale is defined in the space. This leads to weird situations.
For example, the space object has a #default_locale method, but it has no #locales and the environment has a #locales but not a #default_locale, and when I query the defaul_locale
for an space I get a code that is not part of the allowed locales for the master environments.

[103] pry(main)> space = contentful_management.spaces.find('vyk520m9px5z')
[104] pry(main)> space.locales
NoMethodError: undefined method `locales' for #<Contentful::Management::Space:0x00007fdb22b87838>
[105] pry(main)> space.default_locale
=> "en-US"
[108] pry(main)> environment = space.environments.find('master')
[109] pry(main)> environment.default_locale
NoMethodError: undefined method `found_locale' for #<Contentful::Management::Environment:0x00007fdb251fefe8>
[112] pry(main)> environment.locales.all.collect(&:code)
=> ["en-CA", "fr-CA"]

So default_locale is en-US for an space that doesn't has en-US as available locale in any of the environments.

This should not be a big problem, except that when I retrieve a content_type from that environment, the default_locale for that content_type is also wrong.

[115] pry(main)> product = environment.content_types.find('product')
[116] pry(main)> product.default_locale
=> "en-US"

And that problem causes a lot of other bugs, for example: #201, #202, #203

I've read #73 and I know I can use product.client.configuration[:default_locale] = 'en-CA', but that changes the default_locale for the whole contentful management client, and I need to keep it independently for each space.

As a workaround I'm avoiding this problem with this:
product.define_singleton_method(:default_locale) { 'en-CA' } but doesn't feel like a real solution, it's more a temporal patch.
