"Add" takes you to AddScreen, not AddFileScreen

To replicate behaviour:

• From AddScreen, select any media to add a new item
• Complete the form and click "Add"
• Go to the Pending Screen
• Click on "Add" in the nav bar
• You will see the form that you had just filled out

Expected behaviour:

• User should be taken to AddScreen to select media type

Actual behaviour:

• User is taken to previously filled out form
