Fix SecResponseBodyAccess and ctl:requestBodyAccess directives

[victorhora]

Small change to allow for SecResponseBodyAccess and ctl:requestBodyAccess directives to work as intended. Should fix #1531.

@victorhora this PR is breaking current ModSecurity-nginx connector tests:

Funny @defanator, the tests were working for me before. There's a chance I've pushed the wrong code LOL :P. Let me have another a look at it

[victorhora]

Ok, I've pushed the wrong code :P Should be good now unless I screwed up again :P. @defanator If the buildbots pass, please let me know the results of ModSecurity-nginx connector tests. (I can see now we really need Travis integration for those :))

[defanator]

@victorhora yes, connector tests are now passing. I've just submitted an extension to the request body tests for nginx connector here: owasp-modsecurity/ModSecurity-nginx#124

(note that it should be merged after #1886 gets in the v3/master to avoid Travis failures)

Merged! Thanks!
