Bug: Currency identifier doesn't change for Transfer transactions based upon From account's currency

[followingell]

Describe the bug
The currency identifier for the Amount value in the New transfer section is always $ and doesn't change depending on the From account.

To Reproduce
Steps to reproduce the behavior:

1. Go to New transaction.
2. Click Transfer.
3. Swap the From (or To account(s)) to non-dollar account(s).

Expected behavior
I would expect the currency identifier to swap to the currency of the From account since you are transferring a set amount of money from this account to the To account (regardless of the To account's currency).

#1331 was mistakenly closed, so reposting my reply from that to here, which is my proposed solution to this (there's a bit more involved than just defaulting the initial currency):
