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.

This Dangerfile ensures that commit authors write good commit messages.
We also prevent the use of Emoji, since these add no value and may not
always be displayed properly.

Merge commits are currently ignored. In the future we most likely want
to stop using these, but this is a separate discussion, hence we ignore
them for the time being.

The rules enforced by this Dangerfile are based on the article found at
https://chris.beams.io/posts/git-commit/. For more information, refer to
