Arrows repeat their "hit-block" noise whenever they are on a repeater that activates.

Expected:
I expected that the arrow would not continue to make the "hit-block" sound, however they did.

To Reproduce:
1. Create any type of redstone-repeater clock (preferably a fast one)
2. Start the clock
3. Shoot an arrow directly on top of a repeater
4. Notice that every time the repeater is activated the arrow makes the "hit-block" sound

Note: I assume this is because the block is changing, from activated to deactivated, and therefore the arrow is re-hitting the new block, but surely this can be prevented?

Note 2: Tested in 1.8.3 and 1.8.6, survival and creative, with multiple redstone clocks
