Title: Fix visual bug with large file error msg in cms.

This hotfix patches the functionality of the GridFS PR described by @sarina here: https://github.com/edx/edx-platform/pull/5731 by dismissing the error msg when the user uploads a large file and fails, then uploads a regular file. This includes a Jasmine test to cover this case.
