Disable project avatar validation if avatar has not changed

Closes #51053

See merge request gitlab-org/gitlab-ce!21506

CE upstream - 2018-09-04 14:32 UTC

See merge request gitlab-org/gitlab-ee!7230

Every time a column in the projects table is changed, the Avatarable concern
would validate that the avatar file size was under 200K.  This not only delays
the database changes, but it also can lead to unrelated failures if the HTTP
request fails for some reason.
