fix($compile): correct controller instantiation for async directives

This fixes regression introduced by #3514 (9c51d503) - this commit is being
reverted here and a better fix is included.

The regression caused the controller to be instantiated before the isolate scope
was initialized.

Closes #3493
Closes #3482
Closes #3537
Closes #3540
