add missing fixtures to test/functional/wiki_controller_test.rb

Tests fail randomly.

<pre>
  1) Error:
WikiControllerTest#test_show_with_sidebar:
ActionView::Template::Error: undefined method `name' for nil:NilClass
    app/helpers/application_helper.rb:797:in `block in parse_redmine_links'
    app/helpers/application_helper.rb:757:in `gsub!'
    app/helpers/application_helper.rb:757:in `parse_redmine_links'
    app/helpers/application_helper.rb:601:in `block (2 levels) in textilizable'

    app/controllers/wiki_controller.rb:97:in `show'
    test/functional/wiki_controller_test.rb:119:in `test_show_with_sidebar'
</pre>

It can be reproduced by following change.

<pre>
 class WikiControllerTest < ActionController::TestCase
   fixtures :projects, :users, :roles, :members, :member_roles,
            :enabled_modules, :wikis, :wiki_pages, :wiki_contents,
-           :wiki_content_versions, :attachments
+           :wiki_content_versions, :attachments,
+           :issues #, :issue_statuses
