BigDecimal param conversion broke after upgrading from 1.1.0 to 1.3.3

[GProst]

Previously (in 1.1.0) if an empty string was passed it was converted to nil
Now in 1.3.3 it keeps param as an empty string which isn't expected.

I'd expect it to either work as in 1.1.0 or at least return 400 status

Can you please try it against HEAD, I suspect this is fixed in #2067. If not, try writing a spec?

[GProst]

@dblock yeah, seems like it's fixed in master
When do you plan to release 1.4.0?

Add a +1 to #2030
