Plugin Power Saver: Fix Dr. Memory leaks in browser tests.

Plugin Power Saver: Fix Dr. Memory leaks in browser tests.

Power Saver Test Plugin triggers Dr. Memory leaks under Windows. Most likely because the test process is destroyed before the out of process test plugin has a chance to free its Pepper resources (an image data).

This is because the test plugin is trying to draw new frames as fast as it possibly can. There's no reason for the test plugin to draw so many frames. In fact, it only needs one.

Changing the test plugin to draw only one frame fixes the issue for me (locally).
