Add stub methods for FakeApplicationSetting

Closes gitlab-ee#7543

See merge request gitlab-org/gitlab-ce!21662

This gives admins the ability to send a `skip_confirmation` flag in the
`POST /users/:id/email` API endpoint to skip the verification step and
assume the given e-mail address is verified.

Closes #50876

In a migration spec, a default ApplicationSetting object may fail to
create due to an unknown attribute and fall back to
FakeApplicationSetting.  FakeApplicationSetting appears to be missing a
number of methods that are needed
(https://gitlab.com/gitlab-org/gitlab-ce/issues/47491). This commit adds
the ones needed to make an EE spec pass.

Synchronize the default branch when updating a remote mirror

See merge request gitlab-org/gitlab-ce!21653

Migration specs may be missing a column necessary to create an ApplicationSetting
object, which causes the FakeApplicationSetting to be initialized. However, the
project selects a random repository storage via ApplicationSetting#pick_repository_storage,
which isn't present in the OpenStruct.

To workaround this issues, we add a pick_repository_storage method in
FakeApplicationSetting.
