Update to latest release of bazelbuild/rules_apple.

Using the latest rules_apple release fixes the previous continuous integration build failure. This is due to the inclusion of the following commit:
https://github.com/bazelbuild/rules_apple/commit/d24f9791e62ba3edcad69114fe4944e063681b39

Which is required due to a change in bazel 0.15.0. From https://github.com/bazelbuild/bazel/releases/tag/0.15.0:

"non_propagated_deps has been removed from objc_library and apple_binary."
