ApkWorkload: Support implicit activity path

If the activity field of an instance of ApkWorkload does not the '.'
character, it is assumed that it is in the Java namespace of the
application. This is similar to how activities can be referred to with
relative paths:
    com.domain.app/.activity
instead of
    com.domain.app/com.domain.app.activity
