Send breadcrumbs and client error even without transactions

[stefanosiano]

📜 Description

moved breadcrumb sent before span null check in SentryOkHttpEvent
added client error reporting if call root span is null

💡 Motivation and Context

OkHttp breadcrumb and client error were not sent in case the span was not created, like when no transaction is running.
Fixes getsentry/sentry-android-gradle-plugin#606

💚 How did you test it?
