Add missing timestamps to the 'members' table

In 20140914145549_migrate_to_new_members_model.rb we forgot to set the
created_at and updated_at times for new records in the 'members' table. This
became a problem after commit c8e78d97 which
was added in GitLab 7.5. With this migration we ensure that all rows in
'members' have at least some created_at and updated_at timestamp.

Fork to group

Fixes #1592

* fork link always lead to fork page where you select namespace where to fork

See merge request !1253

Before this it would fail because git hooks automatically prepend
things to the path, which can lead the wrong Ruby version to be called
in which dependencies are not installed.

To make sure that this is correct, the forked_merge_requests commented
out test that depends on this change was uncommented.

For that test to pass, it is also necessary to setup the mock server
on port 3001 under test_env.rb.
