Vibrate on block destroy doesn't work in Survival

The vibration on block destruction doesn't work for blocks that take time to break in Survival mode.

Tested on a Google/Huawei Nexus 6P with Minecraft 1.6.0.14 (release version) and 1.7.0.3 (beta).

To reproduce:

• Generate a new Survival world.
• Make sure Settings -> Touch -> Destroy Block (Vibrate) is turned on.
• Break some grass, dirt, or stone (tested by breaking with bare hands)

Expected result:

• when the block breaks on screen, the device should vibrate slightly.

Actual result:

• Device does not vibrate.

This only works for blocks that take time to break: tall grass and oxeye daisies both vibrate when destroyed, because they break instantly. In addition, this doesn't happen in Creative mode: all blocks cause vibration when destroyed.
