Kong: 0.11.0rc2: failed to iterate over APIs plugins

[thochra]

Summary

When trying to iterate over APIs plugins it fails.
Error is

kong-01.dev      | 2017/08/01 15:44:02 [error] 318#0: *7356 lua entry thread aborted: runtime error: /usr/local/share/lua/5.1/kong/core/plugins_iterator.lua:74: attempt to index local 'schema' (a nil value)

After looking at the commit baf69f1f230c77300f3a94be7fc72643caef1e9d I supposed the code perf optimisation failed at some point.

Replacing the file with the previous version and reloading kong did the trick.

Steps To Reproduce

1. Created an API (opened) without plugins configuration + an API (restricted) with a JWT plugin (+ a consumer of course)
2. Did try to use the opened API worked well
3. Did try to use the restricted API it failed with unexpected error
4. Replacing kong/core/plugins_iterator.lua with the 0.11.0rc1 version solved the problem

Additional Details & Logs
