When I select next item's position, it's background blinks to another color and then start evaluating from primary color to destination color

[foxtrotdev]

Reproduce:

1. I have 3 elements in ViewPager
2. I am on item's position 0
3. I click the button which triggers selection next item's position
4. ViewPager selects next position, calls onPageSelected
5. ViewPager sets background color to next one (i.e red->blue)
6. ViewPager starts evaluating color from item's position 0 to item's position 1 (i.e from red into blue)

Look at points 5. and 6. between these operations we can detect blink.

Solution: Remove line: 129-139 from viewPager's listener: PagerActivity.java
