Bad token detection: only transfer as much as is available (#3195)

# Description
The new bad token detection in the driver identified some sell tokens as
unsupported although they are perfectly fine
([example
order](https://barn.explorer.cow.fi/orders/0x2e8eccaad6313a1a2282bed349331a580319854ae9f448aa7290cf5c42ce4d6e9fa3c00a92ec5f96b1ad2527ab41b3932efeda5869442680?tab=overview))

The reason is probably that the test transfer the bad token detection
currently always uses the order's full signed sell amount. This will
fail if the user created a partially fillable order where the sell
amount exceeds their current balance.

# Changes
Adjusted the test transfer to only transfer the
`order.partial.available` amount (when applicable). This value takes
partial fills of the given order and the user's current balance into
account.
