fix($compile): ensure isolated local watches' lastValue is always in sync

When using two-way binding with isolate scope, under some circumstances
the lastValue variable captured in the parentValueWatch function can get
out of sync.

Specifically, if both the value in the origin scope as well as the value
in the isolate scope get independently updated to the same value within
one digest cycle, the lastValue is never updated. This potentially causes
the watch to make the wrong decision as to which side to update on subsequent
passes.

This fixes things by ensuring lastValue is always set to the last seen
value even if the watch's logic was short circuited because there was no
difference between the values in the original and isolate scopes.

fix(input): ensure ngModelWatch() triggers second digest pass when appropriate

Due to an earlier change, ngModelWatch() no longer returns a value to the
caller. This means the digest loop has no way to tell if the watch actually
modified anything and so can not schedule another pass.

This means any watches that watch form or model controller changes
(e.g. watches on form.$valid) that are scheduled prior to an ngModelWatch()
will not be able to see any changes made therin.

This commit fixes this behavior by returning the latest evaluated ng-model
value.

fix(ngInit): evaluate ngInit before ngInclude

The priority of ngInit is adjusted to occur before ngInclude, and after
ngController. This enables ngInit to initiallize values in a controller's
scope, and also to initiallize values before ngInclude executes.
