Safe mode rendering does not correctly prevent using symbol to proc calls
Using methods such as `.each`, a user can pass as an argument a symbol to be called, for example `.each(&:delete)`.
This allows execution of commands that should be blocked by the jail.
A fix proposal in the safemode gem has been suggested: https://github.com/svenfuchs/safemode/pull/23
Once it is merged we should update our version of the gem to the latest one.
