Backpex.Fields.Currency behaving incorrectly

[thanos]

Describe the bug
Backpex.Fields.Currency.render_form/1 shows a blank value. Also when a new value is entered that record is not being updated with the new value.

To Reproduce
Steps to reproduce the behavior:

1. checkout develop
2. Go to /admin/products/ chose a record

This example shows a price of $3,291.41

3. Go to edit it and the field shows price blank:

4. change another field save and the value is retrieved

5. Go back to end and now update the blank price field with a value for example 9999.99 (I'll also update quantity to force an update otherwise there is no change registered by changeset), the original value is not updated.

Both validate and save show the original value, and update only changes quantity.

The issue is also for Currency fields in inline_crud. Saw it when testing pull request #1607 so tried out head and hence this ticket.
Its 22:00 EST here, but I guess can work on it tomorrow when I get home

Hey @thanos, I cannot reproduce this with the latest develop demo.

Are you encountering any console errors?

Yes - it's good in the latest. Sorry for the wild goose chase
