scope does not like false

[blowfishpro]

Steps to reproduce:

Try to add some scope with a false value:

Rollbar.scoped(example: false) { Rollbar.error(Exception.new) }

Observed:

• the example key does not appear on the exception
• If you use any other truthy value (including true, numbers, or anthing else other than nil) it sends correctely

Desired:

• false and true are treated the same way. Maybe nil is different?

Notes:

• The behavior comes from this line - that condition is falsy with false or nil so nothing is done
• Maybe the behavior of false and nil should be thought about here? To me false should be merged in like a normal value and nil indicates that we want to remove that value in the merged hash. But maybe others feel differently?
