Remote devtools doesn't recover from disconnections from standalone app

When I tried to get remote devtools set up for a react native project, I found that nothing would show up in devtools after reloading my app unless I reloaded devtools too at just the right time.

I used the default config: enhancers: getDefaultEnhancers => getDefaultEnhancers().concat(devToolsEnhancer()) for remote and redux-devtools --open to start devtools and the server.

It seemed like the remote client wasn't getting the "START" message from devtools, so I made these patches and they seemed to fix the problem. I didn't look at very deeply at the code, though - I'm sure there's a better way.

@redux-devtools+app+6.1.0.patch @redux-devtools+remote+0.9.3.patch
