find-ing a student then edit-ing the student displays the entire list as a result

As a TA, I will sometimes undergo the following workflow:

1. Find a specific student using the find command
2. Edit the student, say, using the github, class, and edit commands.
3. Visually verify that the changes were made correctly on the GUI.

More concretely, I could execute the following commands:

1. find Omar Holland III (which hopefully results in a single search result)
2. class 1 c/T03
3. edit 1 p/98765432
4. github 1 g/https://github.com/torvalds
5. Finally, look at the UI fields of the student to see if the changes were made.

However, after executing any one of steps 2-4, the GUI ends up displaying the entire list of students. This means that I have to, yet again, execute step 1 to find the student, making this entire workflow extremely clunky.

Instead, the GUI should continue displaying the exact same search results, unless they are no longer valid, i.e., if I changed a student's name.
