'fetch failed' CI failures

[dynst]

CI runs have been failing for a while, all in the same way, possibly as far back as #1602 (though CircleCI won't show the logs for a run that old).

[@cosmjs/stargate]:   5 AuthExtension
[@cosmjs/stargate]: 
[@cosmjs/stargate]:     5.1 account
[@cosmjs/stargate]:       ✗ works for unused account (0.023 sec)
[@cosmjs/stargate]:         - TypeError: fetch failed

A few tests earlier, connections worked fine for these ports:

cosmjs/packages/tendermint-rpc/src/testutil.spec.ts

Lines 39 to 41 in 0d9181d

	export const tendermintInstances = {
	34: {
	url: "localhost:11134",

But the tests using these ports fail:

cosmjs/packages/stargate/src/testutils.spec.ts

Lines 83 to 85 in 0d9181d

	export const simapp = {
	tendermintUrlWs: "ws://localhost:26658",
	tendermintUrlHttp: "http://localhost:26658",

Seems like our Docker container was removed :( The chain does not start anymore

#1652 addresses this by removing the simapp test chains for SDK version 0.44 and 0.45. However, we need to get CircleCI integration restored for to make it work.

This was fixed in the meantime, thanks
