Niels Lohmann 22c8a9554f Keep diagnostic key paths null-terminated ...

Building the token from data() and size() kept an embedded null byte in the
key, and since what() hands out a C string, that truncated the whole message
rather than just the key: to_bson() on a key containing U+0000 reported
"[json.exception.out_of_range.409] (/en" instead of the full explanation.
This broke test-bson under JSON_DIAGNOSTICS.

Constructing from data() alone stops at the first null byte, which is what
c_str() did before, so the message is unchanged -- without requiring
string_t to provide c_str().
