Remove start-Up budget prompts in ProgressFragment

The initial startup prompts are no longer necessary in the
ProgressFragment, because there are Start Up activities that are
implemented.

  in the ProgressFragment as they are no longer necessary.
- implement a flag to clear all of the previous off the stack in the
  StartUpBudgetAmountActivity.
