Fix segmentation fault in aapt2

When passing a single iterator to std::vector::eraase, only element at
that iterator is removed. If no elements are filtered, std::remove_if()
returns the end iterator, attempting to erase() the end iterator can
cause segmentation fault. This bug causes signing test to fail.
