Automatically assigned groups in Crowd have a delayed sync time in Bitbucket

Issue Summary

Users in automatically assigned groups in Crowd experience a delay in getting access when synced with Bitbucket

Steps to Reproduce

1. Create an application called BB on Crowd
2. Connect directory to Bitbucket
3. Run sync
4. Create a user on Crowd and try log in - doesn’t work (expected)
5. Set automatic group assignment in Crowd to stash-users
6. Run sync
7. Try login with user - doesn't work 

Expected Results

User should be able to login and gain access to Bitbucket immediately after the automatic group assignment is set in Crowd

Actual Results

User created in step 7 cannot access BB for 15 minutes (or the time set via the property permissions.cache.group-membership.ttl)

Workaround

Set permissions.cache.group-membership.ttl to a shorter timeframe e.g. 5 minutes
