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

**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.
