Bug/Exception: NoMethodError: undefined method `begin' for nil:NilClass

[bragboy]

This works

Chronic.parse("five years after today")
=> 2023-07-02 17:30:00 +0200

However this does not!

Chronic.parse("five years after 11 May 2017")
NoMethodError: undefined method `begin' for nil:NilClass
from /.../chronic-0.10.2/lib/chronic/repeaters/repeater_year.rb:48:in `offset'

I am fine if it returns nil, but not an exception

It's fixed/works in my rewrite branch.
