fix: disable tracing across the board

[travis]

We currently can't use Sentry's tracing functionality because we overrun our tracing data quota within hours. I'm disabling all tracing and plan on re-enabling it across the board once I've worked out how to use it for the debugging tasks I have on my plate right now.

Note that this does not disable error reporting - that's a separate configuration option and this just disables tracing:

https://docs.sentry.io/platforms/javascript/tracing/

My end goal for this is to have tracing configured at a reasonable percentage for each lambda - most will probably end up around 0.1 but some higher volume functions may need even lower settings.
