Profile view does not display the current session, but the next one

[XavierPaquet-Rapold]

Describe the bug
If the student changes program in the next session, the profile view will display information about the next session, not the current one.

To Reproduce
Steps to reproduce the behavior:

1. Change program for the next session (an internship, for example)
2. Click on the profile view
3. The displayed program is the program for the next session

Expected behavior
The profile view should display the current session, not the last one on the list.

Screenshots

Additional context
The fix will be in profile_view.dart in the getMainInfoCard and getCurrentProgramTile methods, we take the last program, not the current.
