Changing the minimumValue results in incorrect behavior

[DrummerB]

Hi,

If I change the minimumValue of the slider, it doesn't seem to work correctly.

Steps to reproduce:

1. In the Demo project, add these lines in JGScrubbingTestingViewController, after the slider was initialized: _scrubber.minimumValue = 50; _scrubber.maximumValue = 150;
2. Start the app. Slide the slider to the right. For some time it won't slide with the finger for some reason.
