fix(directives): remove an unused import
fix(compiler): Do not store injectors with TaggingElementBinders

TaggingElementBinders are long-lived objects and the injectors are
specific to a View.  By storing injectors, Angular is retaining more
memory than needed.

With this change, injectors are local to a ViewFactory.call() invocation.
