Use features of find command in test.sh

find schemas/ -type f -name "*.json" -not -path "$file" -printf ' -r %p'

And break ajv options to separate lines.

@johnbillion This PR seems to be an anti-john one.

On my local machine I get an error when running composer test with this change:

find: -printf: unknown primary or operator

I can't see an advantage to this change. The current code works fine as it is.

All right. I am not a businessman but a little scientist.

The -printf option is not in POSIX find. It is a feature of GNU find, e.g., on Linux.
