refactor: carve out tx resend timer logic into ShouldResend

Moves the logic of whether or not transactions should actually be
resent out of the function that's resending them. This reduces
responsibilities of ResubmitWalletTransactions and allows
carving out the updating of m_next_resend in a future commit.
