Disable test with Internet Explorer 9

I cannot get IE9 to work on Sauce Labs. I think this is due to an issue
in their stack. Disabling for now, maybe at a future date Sauce Labs
will fix the issue, or someone else will find a workaround.

Detailed notes follow:

For some reason Sauce Labs is adding the capability
`selenium:webdriver.remote.quietExceptions` to the session for IE9 (but
not IE10). This capability is not recognised by IE, and something in the
Sauce Labs stack complains about this. See the [test logs from Sauce
Labs] for more details about this.

I believe this is related to this [issue in IEDriverServer], but I could
be wrong. It's also not clear to me why Sauce Labs is adding this
capability for IE9 but not IE10, so Sauce Labs may change that behaviour
at some point.

As to why IE9 was working with WebdriverIO v4, I believe this is because
Sauce Labs uses a different (legacy) stack in some circumstances.
I think if the client uses the JSON Wire Protocol, which WebdriverIO v4
does, instead of the W3C Webdriver protocol. I couldn't find a way to
use the legacy protocol in WebdriverIO v6.

I also tried downgrading the version of Selenium used by Sauce Labs by
setting ['sauce:options']['seleniumVersion'], however that failed
because it expects the older JSON Wire Protocl, and although the commands
WebdriverIO v6 are backwards compatible with JSON Wire Protocol, when
using the newer W3C stack SauceLabs strips out the JSON Wire Protocol
`desiredCapabilties' key that Selenium v2 requires.
