Unable do generate recursive grammars

[marcospassos]

In continuation of issue #5, we're still getting the following errors trying to generate tests for a grammar with recursive rules:

> grammarinator-process TestLexer.g4 TestParser.g4 -o test
> grammarinator-generate -l test/TestUnlexer.py -p test/TestUnparser.py -r domain -d 1 -n 1 -o output/tests/test_%d.ccl
domain cannot be generated within the given depth (min needed: 5).

domain cannot be generated within the given depth (min needed: 5).

Now seems the warning is reported up to the max depth.

-n defines the number of tests to generate. You should increase -d to change the expected depth.

Sorry, my fault! It worked, thank you!
