Remove duplicate component from sdk snapshot

Previously, an sdk snapshot could contain the following:
* A java_sdk_library_import module, e.g. "foo" which creates component
  modules "foo.stubs", etc.
* A corresponding versioned module, e.g. "sdk_foo@current" which
  created component modules "sdk_foo@current.stubs", etc.
* An internal (to the sdk snapshot) java_import for one of "foo"'s
  components, e.g. "sdk_foo.stubs"
* A corresponding versioned module, e.g. "sdk_foo.stubs@current".

That causes a few problems:
1. The "foo.stubs" is duplicated.
2. The names of the components created by the versioned
   java_sdk_library_import are invalid, as they append the component's
   suffix to the version and not the name before the version.

The latter causes problems when building against prebuilts and fixing
that causes the generated snapshot to be invalid because it contains
duplicate definitions of the "sdk_foo.stubs@current" module. One
explicitly in the Android.bp file and one created by the
"sdk_foo@current" module.

Removing the duplicates from the snapshot causes errors as the name
generated by the snapshot for the component module, i.e.
"sdk_foo.stubs@current" does not match the name generated by the
"sdk_foo@current", i.e. "sdk_foo@current.stubs".

This change fixes them together.
