Accept a beginless range of values for a bare Array type

`requires :a, type: Array, values: ..5` raised `RangeError: cannot get
the first element of beginless range` while the params were defined:
`ValidationsSpec#guess_coerce_type` guessed the member type from
`values.first`, which a beginless Range cannot answer.

A Range now gives the class of its begin, or of its end when it has no
begin. The incompatible-values check that follows still runs against
that guess.
