Require in recursive directives not injecting correct controller

[dquinn40]

The compiler seems to be searching the current element for a directive instead of only parent elements when a required directive is prepended with '^'.

Here is an example in Plunker

Also, there is a work around on Stack Overflow, but it seems this still doesn't work as expected.

This is a duplicate of #4518 --- there's a patch for this, but it's not necessarily a high priority right now.
