Beignet creates tx with fee bellow Minimal if amout is small

[limpbrains]

When the fees are 4,4,4 and you are trying to create tx with small amount (~700 sats) beignet will reduce tx fee and set it bellow 4. It also do not allow to rase it, because of the "Error: Unable to increase the fee any further. Otherwise, it will exceed half the current sending/output amount." rule.

I think this rule should be ignored, beignet should not create tx with such a small fee, it will not be broadcasted

Agreed, this rule has been causing issues. If we want to keep the warning maybe we can have a flag (and string) in the result
of the fee setting method. Then the UI can decide what to do with the warning.

Maybe only use this rule if the amount sent is greater than 10000 sats or something?
