Random seed initialisation not working #170

When mutation and recombination modes are enabled, grammarinator-generate doesn't generate the same output consistently, despite setting --random-seed to a fixed number.

Here is the example command I am using:

grammarinator-generate JSONGenerator.JSONGenerator -r json -o tests/input.in -d 60 -n 1 --random-seed 4 --sys-path . -j=1 --population ../seeds/grts --no-generate

I used a JSON grammar to build JSONGenerator.

Ensure the reproducibilty of the mutation and recombination operators

By fixing the ordering of nodes in annotate and node filtering,
seeded test generation became deterministic in case of mutation
and recombination, too.

Fixes #170.

@bendrissou Thanks for the report. The issue is solved on the latest master, but you need to regenerate your existing corpus to have the expected behaviour. Please check it and tell me if it's working for you.
