web3.version.getNetwork() stops working after changing network with metamask

[chafey]

Observed: web3.eth.getNetwork() never invokes callback after changing network via metamask
Expected: web3.eth.getNetwork() should not silently fail. It should work properly, return error, throw exception or possibly reload the web page if needed when the network is changed via metmask.

Steps to reproduce:

1. Start chrome, create a new tab, open developer tools
2. in console type:
   web3.version.getNetwork(function(err,res) {console.log(err,res);});
   observe the console output of undefined, "1" (for mainnet) is printed
3. Use metmask to change to testnet
4. in console type:
   web3.version.getNetwork(function(err,res) {console.log(err,res);});
   observe that nothing is printed to console, no error is returned and no exception is thrown

#873 related?

I think related to #1148

More related to #873. You want a way to detect manual network changes.

This is actually bc metamask disconnects from the dapp when changing networks and we are not forcing the dapp to reload.

I had web3 1.0.0 beta and that was causing an error.
Installing version 0.19.0 like this fix the issue:

npm install --save web3@^0.19.0

And it worked for me.
