JSONRPCProvider breaks if network is "any"

[dmihal]

I believe #1371 has introduced a bug regarding using Web3Provider with "any" network.

If a provider is constructed:

const library = new Web3Provider(provider, 'any')

Then the BaseProvider will query the network inside the constructor.

ethers.js/packages/providers/src.ts/base-provider.ts

Lines 483 to 487 in c0daf43

	// If network is any, this Provider allows the underlying
	// network to change dynamically, and we auto-detect the
	// current network
	defineReadOnly(this, "anyNetwork", (network === "any"));
	if (this.anyNetwork) { network = this.detectNetwork(); }

However, this will fail, because the JSONRPCSigner doesn't set _eventLoopCache until after super()

ethers.js/packages/providers/src.ts/json-rpc-provider.ts

Lines 308 to 310 in c0daf43

	super(networkOrReady);
	this._eventLoopCache = { };

And the following error is thrown:

Uncaught TypeError: Cannot read property 'detectNetwork' of undefined
    at Web3Provider.detectNetwork (json-rpc-provider.ts:331)
    at new BaseProvider (base-provider.ts:487)
    at new JsonRpcProvider (json-rpc-provider.ts:308)
    at new Web3Provider (web3-provider.ts:119)

I've confirmed and reproduced this, and will get to it ASAP.

Thanks! :)

This has been addressed in 5.1.3. Can you try it out and let me know?

Thanks! :)

5.1.3 seems to be working for me, thanks for the quick fix!
