Default perspective is AlgebraGraphics when enter into a group for the first time #34

Tested 9/22/18 @ 4:04 MathNetTest Server
I am sending multiple perspectives to students. When I send different than the AlgebraGraphics perspective, e.g. Graphics1 and Graphics2; or Graphics1 and spreadsheet, the perspectives goes to all students already in the groups, but when a new student, student1, logs in and then enters into a group, their view defaults back to Algebra and Graphics perspectives. This means the teacher has to resend the activity to the group and undoes any of the students' previous work.
I tried it with the following perspectives: Algebra+Graphics1+Graphics2, Graphics1+Graphics2, Algebra+Graphics1+Spreadsheet, and Graphics1+Spreadsheet.
All resulted in the problem described above.
