Fix out-of-bounds read in json_lex_string
Commit 3838fa269 added a lookahead loop to allow building strings multiple
bytes at a time. This loop could exit because it reached the end of input,
yet did not check for that before checking if we reached the end of a
valid string. To fix, put the end of string check back in the outer loop.
