[MDS-6139] Don't disable IRT/final app tab when "Start" button is enabled

[taraepp]

Objective

• made a mistake last PR!
• I kinda forgot that disabling the tab on project overview also effectively disables the start button
• because it does a query selector to find the tab and does a .click() on it
• previously, I did try just running the same function from clicking the tab when you click start and it didn't work
• don't want to spend too much time on that rabbit hole though
• I went to CORE to make the "View" behaviour more similar (ie: able to click the tab even if button is disabled if summary was submitted) but ended up reverting it because the IRT tab behaviour was VERY confusing (first it crashed until I added that ? and then it showed Loading because loading is dependent on the IRT having a guid and I thought it was a bad idea to play with that logic)
