Fix issue with Kernel#silence_stream leaking file descriptors

Calling Kernel#silence_stream creates a new file descriptor which isn't
closed after it is used. As a result calling silence_stream multiple
times leads to a build up of loose file descriptors and can cause issues
in environments where garbage collection isn't run often.

Fix the merge of a label class defined inside the block

Make sure that spring is loaded in development only

This will fix the regression added on

before the application

This test is a regression test to

polymorphic belongs_to association with touch: true updates old record correctly

Example: Given you have a comments model with a polymorphic commentable
association (e.g. books and songs) with the touch option set.
Every time you update a comment its commentable should be touched.
This was working when you changed attributes on the comment or when you
moved the comment from one book to another. However, it was not working
when moving a comment from a book to a song. This is now fixed.

Set `i18n.enforce_available_locales` before any other configuration option.

Discoverd by #13175.

docs: Replace an unpleasant grammatical construct.
