Remove get_pages() from uncached functions in …

[davecpage]

…WordPress.VIP.RestrictedFunctions

It is cached and is no longer on the VIP restricted list.

Fixes #569

@davidpagepsycle The tests are currently failing:

There was 1 failure:

1) WordPress_Tests_VIP_RestrictedFunctionsUnitTest::testSniff

[LINE 60] Expected 1 error(s) in RestrictedFunctionsUnitTest.inc but found 0 error(s).

[LINE 61] Expected 1 error(s) and 0 warning(s) in RestrictedFunctionsUnitTest.inc but found 0 error(s) and 1 warning(s). The warning(s) found were:

 -> get_children is discouraged in favor of creating a new WP_Query() so that Advanced Post Cache will cache the query, unless you explicitly supply suppress_filters => false. (WordPress.VIP.RestrictedFunctions.get_posts)

I guess you need to update the tests to reflect this change.

@JDGrimes Ah, forgot about the Travis checks. I've made changes to the tests so no failures now.
