Cannot run migrations on latest master due to !774

After !774 (merged) was pulled into master, I updated my local copy and tried to run rake db:migrate, but was greeted with this error:

gitlab master % rake db:migrate
/Users/tsigo/.rbenv/versions/2.1.6/lib/ruby/gems/2.1.0/gems/activemodel-4.1.9/lib/active_model/attribute_methods.rb:435:in `method_missing': undefined method `session_expire_delay' for #<ApplicationSetting:0x007ffc4cef16b8> (NoMethodError)

Basically you can't migrate because the field that the migration would create doesn't exist yet. It's a chicken-and-egg problem. This is a blocker for 7.12, and I've got a fix ready, I just want to make sure I'm not the only one seeing it.

mentioned in merge request !808 (merged)

Just ran into this too. Please get this in!

@stanhu Finally got CI running, so we'll see. If you need to get work done in the meantime just comment out that first block in config/initializers/session_store.rb. (You probably figured this out already, but just in case!)

Must be fixed. Just add column_exists check in initializer

@dzaporozhets !808 (merged) should fix.

@rspeicher awesome! THank you for fixing it!
