tests: virjson: Remove spaces from 'very-hard' parsing example

The example is rather long and upcomming patch will check whether the
string can be formatted back. As the formatted string lacks spaces and
adding the 'expect' string with spaces would be rather long, just drop
spaces from this test case.

There are other test cases which do contain spaces.
