Fix Raven.setUserContext typescript definition.

[fabien0102]

The Raven.setUserContext is actually very permissive so any may be a better option here.

Additionally you can provide arbitrary key/value pairs beyond the reserved names and those will be stored with the user.

Note: I tried the actual tested payload on sentry, and I have the data perfectly display 😉

From travis:

Running "config:ci" task
No SAUCE_USERNAME env variable defined.
No SAUCE_ACCESS_KEY env variable defined.

I don't think that it's link to my PR 🤔
