Redirect chrome://extensions to the new chrome://settings/extensions (attempt 3).

I split up an API test because it times out (it is doing too much).

The other two modifications to the tests were needed because they were trying to open chrome://extensions in incognito.

In one case, the test just needed any page (so I switched to about:blank) and in the other we are testing for a condition that cannot happen anymorebecause chrome://extensions could be loaded in incognito but chrome://settingsdoesn't allow that -- it shunts the request to the non-incognito profile.

The test was testing that we don't crash in incognito, so I removed that test. Also change the URL for the Extension Settings page fromchrome://settings/extensionSettings  ->  chrome://settings/extensions.

BUG=87377, 96836
TEST=Well... type in chrome://extensions and notice it redirects.
TEST=chrome://settings/extensions (or chrome://extensions) should take you to the extension settings page, and chrome://settings/extensionSettings should not.
