Fix bug in construct_nfa

Intermediate final states were being left in by add_fsa(); we always
want to mark the added FSA's final state as non-final.

Use runtime asserts instead of error returns in desugar.c
...
The error paths are not tested and are mostly for NULL allocations so
it makes more sense to use runtime asserts for now for simplicity's
sake.

Assert success of alloc in deep_copy_* loops

Returning false here would leave the destination sequence in an
invalid state and may lead to leaked memory; until this is solved
properly it is safer to assert().
