Change shada reencoding tests to check for correct handling of UTF-8 and binary strings. Delete enc=latin1 json tests.
The test hit wait_return if x or .x.swp exists in the project root directory.
It is otherwise impossible to determine which test failed sanitizer/valgrind check. test/functional/helpers.lua module return was changed so that tests which do not provide after_each function to get new check will automatically fail.
