[Test coverage] Customer addresses

[naydav]

Need to cover with API-functional tests cases in

customer: Customer @resolver(class: "Magento\\CustomerGraphQl\\Model\\Resolver\\Customer") @doc(description: "The customer query returns information about a customer account") @cache(cacheable: false)
deleteCustomerAddress(id: Int!): Boolean @resolver(class: "Magento\\CustomerGraphQl\\Model\\Resolver\\DeleteCustomerAddress") @doc(description: "Delete customer address")
updateCustomerAddress(id: Int!, input: CustomerAddressInput): CustomerAddress @resolver(class: "Magento\\CustomerGraphQl\\Model\\Resolver\\UpdateCustomerAddress") @doc(description: "Update customer address")

Test cases:

\Magento\GraphQl\Customer\CreateCustomerAddressTest
- createAddressWithInvalidInput (data provider with: missed `input`, empty `input`, not array `input` parameter)

\Magento\GraphQl\Customer\DeleteCustomerAddressTest
- deleteCustomerAddressIfAddressIdIsInvalid (id is missed, id is empty)
- deleteAnotherCustomerAddress (attempt to delete address which belongs to another customer)
- testDeleteCustomerAddressIfAccountIsNotConfirmed
- testDeleteCustomerAddressIfAccountIsLocked (\Magento\GraphQl\Customer\UpdateCustomerTest::lockCustomer)

\Magento\GraphQl\Customer\UpdateCustomerAddressTest
- updateCustomerAddressIfAddressIdIsInvalid (id is missed, id is empty)
- updateCustomerAddressWithInvalidInput (data provider with: missed `input`, empty `input`, not array `input` parameter)
- testUpdateNonExistCustomerAddress
- updateAnotherCustomerAddress (attempt to update address which belongs to another customer)
- testUpdateCustomerAddressIfAccountIsNotConfirmed
- testUpdateCustomerAddressIfAccountIsLocked

\Magento\GraphQl\Customer\GetAddressesTest
- testGetCustomerAddressIfAccountIsNotConfirmed
- testGetCustomerAddressIfUserIsNotAuthorized
- testGetCustomerAddressIfAccountIsLocked
