Don't run networkInfo tests against ie11

[evanfarina]

Description

The stubbing of networkInfo doesn't play nicely with ie11 which complains with the following message: Assignment to read-only properties is not allowed in strict mode. After speaking with Gary, we've decided to skip these tests in IE.
