common: Sentry should report exceptions in initialising environment

[istreeter]

Concerning this method here. Currently, the sendToSentry function is called whenever an exception is raised inside the environment.use block. However, if the exception is raised when creating the environment then the program flow never gets as far as this block.

The correct implementation should look more like this:

environment.use { env =>
  // do something with environment
}.recoverWith {
  case e: Throwable =>
  // send to sentry here
}

But it can't be exactly like that, because currently the sentry client is part of the environment.
