Include more info about account, timeframe, etc. in Sentry errors

[Mr0grog]

We can usually figure out a lot about the configuration of a scraper run that errored from other anecdotal info in the error, but we should use Sentry’s breadcrumbs or contexts to be more explicit about it.

Specifically, we should make sure to include:

• Timeframe (--before and --after)
• Start time (of the actual run, not the timeframe being scraped)
• Account name (relatively anonymized, like versionista1, versionista2, instead of e-mail)

We are currently on a deprecated version of the Sentry SDK (see #162). Relevant docs for it are at: https://docs.sentry.io/clients/node/
