parameter filtering is inconsistent with rails

[tamird]

We observe that bugsnag is filtering parameters with semantics completely different from those used by rails. For instance, our rails application is configured to filter out the parameter "q", which in rails is an exact match, while bugsnag filters all strings including the character "q" (think action_dispatch.request.*).

Here's the responsible line in the bugsnag railitie: https://github.com/bugsnag/bugsnag-ruby/blob/master/lib/bugsnag/railtie.rb#L2

And Rails' ParameterFilter: https://github.com/rails/rails/blob/master/actionpack/lib/action_dispatch/http/parameter_filter.rb
