Update Psych::safe_load Method Signature (#823)

* fix error when parsing config file

YAML parser returns wrong number of arguments(given 4, expected 1),
this fix removes the extra parameters, while still passing in the
allowAliases flag.

* Deprecate Ruby 2.5; bump min Ruby version in gemspec; bump Ruby versions in Travis test matrix
