TEST_RANGE flatten error when only single argument

[KalleDK]

This line seems to make trouble, if you only have on arg

Unity/auto/generate_test_runner.rb

Line 155 in 61f4428

arg_combinations.flatten.join(', ')

TEST_RANGE([0, 2, 1])
void testFlaf(int num) {}

undefined method `flatten' for 1:Integer (NoMethodError)
from ./generate_test_runner.rb:155:in `map'

If it's replaced with

if arg_combinations.kind_of?(Array)
    arg_combinations.flatten.join(', ')
else
    arg_combinations
end

I don't know ruby ! So if there is a more correct way - or something that I don't know please take this only as a suggestion

I made a PR for this, see #554.
