Missing await

[lautarodragan]

In this line isValidSignature is missing an await. The promise returned is truthy, always evaluates to true.

poet-js/src/VerifiableClaimSigner.ts

Lines 69 to 70 in f50a701

	if (isValidSignature(signedClaim)) return signedClaim
	throw new IllegalArgumentException('Claim signature is invalid')

This hasn't been an issue. This code is probably more suitable for a unit test. We could just remove it here and add a unit test.
