fix occasional errors we see when generating a uuid using uuid library by switching to securerandom

[iiilx]

example of the error we were seeing in prod:

NoMethodError: undefined method `unpack' for nil:NilClass
/usr/local/bundle/ruby/2.7.0/gems/uuid-2.3.9/lib/uuid.rb:377:in `read_state': undefined method `unpack' for nil:NilClass (NoMethodError)
	
from /usr/local/bundle/ruby/2.7.0/gems/uuid-2.3.9/lib/uuid.rb:333:in `block in next_sequence'

maintainers of uuid gem did not address this so people switched to SecureRandom: assaf/uuid#28
