Feature: Multisign SignAs where user has set RegularKey

[dangell7]

In order to perform multisign where one of the signers has a RegularKey enabled you must signAs using the account while signing the transaction with the delegate.

const signer1 = derive.familySeed('') -> This user has set their `RegularKey` to signer1Delegate
const signer1Delegate = derive.familySeed('')
const regKeySig1 = sign(
    accountSetTx,
    signer1Delegate.signAs(signer1.address as string)
  )

The fix might occur here:

Xaman-App/src/screens/Overlay/Vault/VaultModal.tsx

Line 293 in e6b13d8

signerInstance = signerInstance.signAs(preferredSigner.address);

This account needs to be the signer1 address.
