test classes fail: returning `\n` newline characters

[dcinzona]

testClone1()
testToString()

Personally, I wouldn't try to format (prettify) the query string because that will introduce a bunch of problems when trying to test the final query string.

I have PR ready - should I send it? As it doesn't make sense .. or we could overload toString to sth like
toString(Boolean beautify);

I like the overload idea
Gives the dev options.
