misc/trace: update trace viewer html 

The old trace-viewer is broken since Chrome 49:
https://bugs.chromium.org/p/chromium/issues/detail?id=569417
It was fixed in:
https://github.com/catapult-project/catapult/commit/506457cbd726324f327b80ae11f46c1dfeb8710d

This change updates trace-viewer to the latest version
(now it is called catapult).

This version has a bug in the lean config that we use, though:
https://github.com/catapult-project/catapult/issues/2247
So use full config for now (it works, but leads to larger html).
When the bug is fixed we need to switch back to lean config (issue #15302).

We are supposed to use --config=lean (produces smaller html),
but it is broken at the moment:
