fix: When deleting account and transferring funds switch to internal

[obany]

Description of change

If you are deleting an account that has funds the button says "Internal Transfer" but it doesn't actually switch to internal transfer. This fix adds an isInternal flag to send params which will initialise the UI to the correct location.
