@dennis00010011b could we add e2e tests

• that unlocked account is changed to contract after reject/reject all*/submit tx
• that unlocked account is not chnaged in other cases

*for reject all case unlocked acount is changed, if all txs to the same contract.

It goes back to the sender account after contract execution if 'Buy ether' option had been selected during the submitting transaction.
Steps:

1. Import contract 0x215B2Ab35749e5A9f3EFE890DE602fB9844E842f, Sokol
2. Select method transfer
3. Select executor the account with 0 balance. Click 'Next'
4. Click button 'Buy ether'
5. Click arrow button and return to the transaction screen
6. Click button arrow or reject/reject all
7. Observe account's address

Expected: should be contract's address
Actual: executor's address

Arrow button always leads from 'Confirm transaction' screen to executor account. Should leads to contract account

Yes, from account selection until a decision on tx: acception, rejection we are under executor. This is implemented by design.
