Description of problem:

Encountered a content sync problem while I was away.  When I came back after 2 hours, I clicked Redeploy on the Content Sync 

Version-Release number of selected component (if applicable):

QCI-1.0-RHEL-7-20160901.5

How reproducible:

100% when these 2 things occur

Steps to Reproduce:
1. Install/configure QCI [RPM install in this case]
2. Deploy RHV
3. When Content Sync error occurs, wait about 2 hours
4. On Content Sync page, try to Redeploy

Actual results:

Nothing on screen - just blinks for a moment

Expected results:

Attempted redeployment

Additional info:

Workaround:
* Navigate to another part of Satellite: Hosts > All Hosts in my case
* Quickstart Cloud Installer > Deployments
* Select deployment
* Redeploy

Content sync error was:
An error occurred during the sync 
{"expected_size"=>1205972, "error_code"=>"size_mismatch", "actual_size"=>1024780, "unit_key"=>{"epoch"=>"0", "version"=>"3.10.0", 
"name"=>"perf", "release"=>"123.1.2.el7", "checksum"=>"7752be3e7d286718f69a831f7f2d4a60a66e4de4", "arch"=>"x86_64", "checksumtype"=>"sha1"}}

Problem seems to be in /var/log/foreman/production.log:

So navigating gets the new CSRF token?
