From: Adrian Frances <adrian.fran...@netduma.com>
According to the lua man page for lua_next, it is not
advised to call lua_tolstring when iterating through a
table with lua_next.
When iterating a table in ubus_lua_format_blob_array,
we end up calling lua_tostring, which inside calls
lua_tolstring, converting all non-string keys to a key
format, even for the caller.
This patch fixes the issue by restoring the original key
