Creating wallet step 3: error messages not cleared after a change

[TJ-BitCanna]

When an user puts in a wallet name which has already been taken and/or a wrong password an error message is shown (good!).

When the user changes for example the wallet name to an unique value and tries to save again, the error messages don't change.

Behaviour to be added:

• when the user changes something on the screen and pushes "save" again, the error message should be cleared before checks are made if the data is ok. New error messages to be posted when still issues are present.

The "bad password" error message does not disappear, even when surely putting in the right one

Fixed and can be tested android/ios
