 The first of these tests works as expected, but the second generates an
 "Undefined index" notice.

 {{{#!php
 function test_get_call_count_action() {
         $action = rand_str();
         $ma = new MockAction();

         add_action( $action, array( $ma, 'action' ) );
         do_action( $action );

         $this->assertSame( 1, $ma->get_call_count( 'action' ) );
 }

 function test_get_call_count_filter() {
         $filter = rand_str();
         $ma = new MockAction();

         add_filter( $filter, array( $ma, 'filter' ) );
         apply_filters( $filter, rand_str() );

         $this->assertSame( 1, $ma->get_call_count( 'filter' ) );
 }
 }}}

 The attached patch attempts to fix the notice and allow passing filter
 names to `get_call_count()`.
