Feature: Moving project solutions to Hotwire final tweaks

Because:
* A few final touches before we start rolling this out to users.

This commit:
* Move the add solution button hook outside of the current users solution conditional - this is needed for the button to display correctly when the user deletes their solution after refreshing the page.
* Change "Add submission" button text to "Add solution" - to fit the solutions title.
* Add a hidden class to the drop down so it does not flash visible for a brief moment during re-render
