Extra Song UI - Star Power phrases with no notes are counted towards total

[Biendeo]

Describe the bug
When playing a song that contains star power phrases that have no notes attached, the total number of star powers represented in Extra Song UI's total star powers counter appears to count that number rather than the actual number that can be played.

To Reproduce
Steps to reproduce the behavior:

1. Play Rock Band 1's Are You Gonna Be My Girl on expert guitar.
2. The SP total counter should say 17, but only 15 are playable in the song.
3. The end of song screen should correctly say 15/15 though if you FC.

Expected behavior
For this song in particular, there should be 15 star power phrases, as seen on the end of song screen, so the total counter should say 15.

Environment (please complete the following information):

• OS: Windows
• Clone Hero Version: v0.23.2.2
• Using the new Clone Hero Launcher: no
• Tweak version: v1.2.0.13
