Get rid of storage tracker layout tests

Reviewed by Darin Adler.

These tests are very flaky since they expect to be run in order. Furthermore, they were testing a WebKit Mac SPI
that is pretty hard to test reliably, due to its "design". It's not worth trying to make these tests work
or to rewrite them in Objective-C (which would be the right thing to do), so just get rid of them.
