docs: Asserts that the given {@code List} starts with the given sequence of objects, without any other objects between
  them. Similar to <code>{@link #assertContainsSequence(Description, List, Object[])}</code>, but it also verifies
  that the first element in the sequence is also the first element of the given {@code List}.
  
  @param description contains information about the assertion.
  @param actual      the given {@code List}.
  @param sequence    the sequence of objects to look for.
  @throws NullPointerException     if the given argument is {@code null}.
  @throws IllegalArgumentException if the given argument is an empty array.
  @throws AssertionError           if the given {@code List} is {@code null}.
  @throws AssertionError           if the given {@code List} does not start with the given sequence of objects.
