Checks of events emissions are not working well in tests due to wrong use of chai matchers

[miguelmtzinf]

This is an example of a chai matcher not working well, because it is not checking the event emissions.

aave-v3-core/test-suites/aave-oracle.spec.ts

Lines 48 to 54 in 94e571f

	expect(
	await aaveOracle
	.connect(poolAdmin.signer)
	.setAssetSources([mockToken.address], [mockAggregator.address])
	)
	.to.emit(aaveOracle, 'AssetSourceUpdated')
	.withArgs(mockToken.address, mockAggregator.address);

It should be done using as follows:
await expect(txPromise).to.emit(contractArtifact, eventName).withArgs(...)
