Specify rounding mode when rendering Monetary entity tokens

Specify rounding mode when rendering Monetary entity tokens, avoids RoundingModeException

Overview

Found when investigating why Schedule Reminders would not send.
Rendering Monetary tokens was failing due to no rounding mode being set.

Before

Formatting Money amounts is attempted in token rendering without rounding mode specified. If rounding is required, Brick will instead throw an exception, because it needs to be told how to round.

The conditions under which this is required are not especially clear, however it's probably a result of implementing Tax.

After

Specifies a rounding mode when rendering monetary amounts for tokens. Does not throw an exception when it needs to round.

Technical Details

One line change... I also reviewed other places where Brick\Money\Money::of is in use and found most other places are already specifying HALF_UP as the rounding mode, which makes sense.

We do this in the Money::format() function so this makes sense

We just forked 5.72 but I think it's reasonable to target this against 5.72 as it could be experienced as a regression so I changed the branch
