Fix BC break with DoctrineType::reset()
Fix BC break with DoctrineType::reset()

Fixes BC break with mistakenly removed `kernel.reset` tag from
`form.type.entity` service, because `DoctrineType` implements
`ResetInterface`, but this service is not autoconfigured, so
the `kernel.reset` tag won't be added automatically.

This BC break was introduced in version 1.11.0 in commit 6b25ea4
