Fee - Fee Category is added multiple times

[umairsy]

Steps:

1. Created new Program Enrollment.
2. Selected Semester 1 and 2, and Due Date. But did not select exact Fee Structure in the Program Enrollment.
3. Saved Program Enrollment. On Save, Fee record was created.

Issue:

In the Fee record created for both the semester, one fee category is added multiple times.

This error only occurs if I leave Fee Structure field blank in Program Enrollment. If specific Fee Structure is selected, then Fee record is created correctly.
