fix($compile): only pass isolate scope to children that belong to the isolate directive

I had to fix one unit test, as it assumed the broken behavior, where application template gets the
isolate scope of other (isolate) directive, rather than the regular scope.

BREAKING CHANGE: Child elements that are defined either in the application template or in some other
directives template do not get the isolate scope. In theory, nobody should rely on this behavior, as
it is very rare - in most cases the isolate directive has a template.
