Uncaught JsonRpcProvider exceptions in v5

[mrwillis]

Not sure if this is something on our end or not but since upgrading to v5, if there is some provider error, it seems to not bubble up in the local function but instead throws an uncaught exception which I can't quite track down. For example:

and

base-provider.ts:2 Uncaught (in promise) Error: missing response (requestBody="{\"method\":\"eth_blockNumber\",\"params\":[],\"id\":127,\"jsonrpc\":\"2.0\"}", requestMethod="POST", serverError={}, url="https://rpc-mumbai.matic.today", code=SERVER_ERROR, version=web/5.0.11)
    at Logger.makeError (index.ts:205)
    at Logger.throwError (index.ts:217)
    at index.ts:234
    at Generator.throw (<anonymous>)
    at rejected (index.ts:2)

Still trying to gather more info. Perhaps I need to do await provider.ready?

Thanks

Please see #1208. I got a fix in for this last night and am just doing some final testing and reviews. :)
