Use proper render method in static markup event listener test

[nhunzaker]

The renderToStaticMarkup test that checks for event listeners was using the wrong render method.

Coverage remained the same at 87.233% when pulling e9e101b on nhunzaker:nh-static-markup-test into 7b247f3 on facebook:master.

Thanks.

There's a couple of other calls to renderToString left inside the describe('renderToStaticMarkup') block:

• react/src/renderers/dom/server/__tests__/ReactServerRendering-test.js

  Line 423 in 40c90a6

  var markup = ReactServerRendering.renderToString(

• react/src/renderers/dom/server/__tests__/ReactServerRendering-test.js

  Line 452 in 40c90a6

  ReactServerRendering.renderToString.bind(

Not sure if they should be testing renderToStaticMarkup instead, or if they should be defined in a different place in the file?

Need to ask the authors.
