bump switchman

refs AE-1

Test Plan:
1. make sure you've got redis configured as your cache. MultiCache.cache
   should return a ActiveSupport::Cache::RedisCacheStore
2. have a setup where the local ID of a root account on one shard matches
   the local ID of your SiteAdmin account on another shard. For example,
   in my setup the SiteAdmin account lives on Shard 1 and has a local ID
   of 1, and on Shard 2 I have a root account with a local ID of 1.
3. bundle install on a branch with pre-3.4 switchman
4. clear redis: redis-cli flushall
5. start a rails server and navigate to your site admin account in the
   browser. For me, that's

   <shard 1 domain>/accounts/site_admin

6. navigate to your root account on the other shard with the same local id
   as the site admin account:

   <shard 2 domain>/accounts/<root account local id>

   Verify it takes you to the correct account.

7. stop your server, switch to this branch (switchman 3.4.2), do a
   bundle install, and start your server. Navigate to the root account on
   shard 2 again:

   <shard 2 domain>/accounts/<root account local id>

   Verify it takes you to the correct account.
