Check if the Rails.backtrace_cleaner method exists before calling it.
We've got a report from a user that the method call fails with a
NoMethodError in a Sinatra app using the activesupport and actionmailer
gems version 5.2.0.
I was unable to reproduce in the test setups, but I can see a scenario
where this could fail. To make sure we don't cause this kind of error in
such a scenario, check if the Rails module listens to the
backtrace_cleaner
method before calling it.appsignal/test-setups@d484b36
