Point and spot lights clip prematurely when they approach the top or the bottom edge of the camera.

Repro steps:
1. Open LightingIssue from attached project.
2. Select the camera in the hierarchy and rotate it on the X axis to move the green point light up and down the screen.
3. Notice how the green point light clips before it reaches the edge of the screen.

Expected outcome: light clip plane to align with the camera's.

Notes:
- Regression in 5.4.0b4; issue not present in 5.4.0b3
- Happens only in Forward rendering.
- The light's range seems to also be determining its clipping range (see LightIssue_SpotLight.gif)
