Error messages under input fields are not updated

[Jakub-CZ]

Description

As user types into a validated text field, if the new string is still invalid but the error message (reason of invalidity) changed,
the message is not updated to reflect the new reason.

Version

c52d669

Steps to reproduce

1. DAO -> Governance->Make Proposal->Proposal for changing a parameter
2. Select BTC maker fee
3. While the current value is 0.001, gradually type 0.0011. Notice the error messages displayed for each partially entered value.

Expected behaviour

The error message reflects the reason why the value in the text field is invalid.

E.g.: going from 0.00 to 0.001 should switch from "dust limit not allowed" to "must be different from current value".

Actual behaviour

The first error message that "snaps in" and is not updated when the reason for invalidity changes. One of the ways to get a correct message is to focus out of the field and then refocus the field again.

Screenshots

Below are the states of a field as the value 0.0011 is being entered, and then cleared again.
