Error when setting user context since 1.6.0: array_merge(): Argument #2 is not an array

[tremby]

Since #387 I get an error when setting the user context.

The monolog RavenHandler stores $previousUserContext which in my app ends up being null (rather than its initial value of false). This happens when RavenHandler sets it to the value of $this->ravenClient->context->user, which at this point is null.

It then calls user_context (see https://github.com/Seldaek/monolog/blob/1.22.0/src/Monolog/Handler/RavenHandler.php#L189 which is the latest release right now -- current master has slightly different code but the same issue) with that null in the $data, which is not an array, hence the error.

I don't know if this is a bug with sentry-php or with the monolog RavenHandler, but it's the recent change in behaviour which is causing the error.

Dup of #388, I believe.

Yep, should be fixed in 1.6.1

Oh wow, reported just as I typed mine. Thanks!
