[IE9] tests/core/selection/fake test is not passing on IE9 when console window is opened.

Run: ​http://test.ckedtior.dev:1030/tests/core/selection/fake Test Fake-selection bookmark mark as not faked when no enclosed node found. (#13280) is not passing when console window is opened.

This is caused (probably) by this code:

if ( window.console ) {
	// Override to avoid logging the CKE's warning about selection not being fake any more,
	// so the console stays clean when the test passes.
	var consoleLogSpy = sinon.stub( window.console, 'log' );
}

When console is opened we try to stub console.log method but sinon library fails on native IE9 implementation and throws an error Attempted to wrap object property log as function. Similar problem: #13917.

Pushed ​branch:t/13916. On IE <= 9 sinon library has problems with stubbing window.console functions. selectBookmarks function is using CKEDITOR.warn method now, so it can be used for stub instead of console.log (which is executed beneath).

Fixed with ​git:26a9fb2c6f (merged to master).
