Bug 32045: Use bootstrap tabs to select item tab

Bug 32045: Use bootstrap tabs to select item tab

When the form to add orders from a staged file is validated, we use
toptabs functionality to switch to the item tab if there are missing fields.

The display now uses bootstrap tabs, so the JS is throwing an error:
Uncaught Error: cannot call methods on tabs prior to initialization; attempted to call method 'option'

This patch simply switches the call to switch tabs

To test:
1 - Stage a file for import
2 - Either use Marc(Item)FieldsToOrder to populate the orders
    or select a budget on the third tab
3 - View the second tab, items info, confirm itemtype is required, but don't populate it
4 - Attempt to save order, nothing happens
5 - Check the JS console (F12)
6 - Note the error:
    Uncaught Error: cannot call methods on tabs prior to initialization; attempted to call method 'option'
7 - Apply patch
8 - Cancel and add from staged file again
9 - Select a budget and save
10 - You now get an error popup: Some required item subfields are not set
11 - Confirm after the error you are shown the items tab
12 - Select itemtype
13 - Save
14 - Confirm orders added successfully
