cardano-up context env does not show updated dynamic ports after cardano-up down and cardano-up up

[verbotenj]

The command cardano-up context env does not update the dynamic ports after executing the sequence of cardano-up down followed by cardano-up up.

• Run cardano-up context env
• Execute cardano-up down
• Execute cardano-up up
