We might want to instead modify api.UsersByNames

[maxice8]

@profclems, this affects everything that uses api.UserByName, and api.UsersByName uses it so the affected places are:

commands/mr/update/mr_update.go:				users, err := api.UsersByNames(apiClient, assignees)
commands/mr/create/mr_create.go:				users, err := api.UsersByNames(labClient, opts.Assignees)
commands/issue/create/issue_create.go:			users, err := api.UsersByNames(apiClient, opts.Assignees)
commands/mr/list/mr_list.go:				users, err := api.UsersByNames(apiClient, assigneeNames)

Great one! I like this solution.
