new metamask update breaks getReceipt

[nionis]

I am not sure if this is the right place to report this, but I have unsuccessfully tried to replicate this bug on other dapps which don't use web3x.

Last night there was a new update for metamask (7.7.0) that breaks "newBlockHeaders" subscription,

web3x/web3x/src/eth/send-tx.ts

Line 66 in 9b1fb49

.on('data', async (blockHeader: BlockHeaderResponse, sub) => {

doesn't fire.

I can confirm it works on previous versions, and that on my end I haven't changed my source code.
