Wiki repository size isn't updated after migration
Problem
For projects migrated via GitLab Direct Transfer, the Wiki report size reports 0 bytes, although the wiki was successfully migrated.
Proposed solution
We should trigger a calculation of the Wiki size after the migration.
Since Project#after_import is called by GitLab Direct Transfer at the end of the migration process, updating Project#after_import
to calculate the Wiki size should be enough
ProjectCacheWorker.perform_async(project.id, [], [:repository_size, :wiki_size])
