Fixed bug in Summary.soma_adat() operations

- these operations: min(), max(), any(), range(), etc.
- would return the incorrect value due to
  an `as.matrix()` conversion under the hood
- now skips that conversion, trips a warning,
  and carries on
- triggers an error of non-numerics are passed
  as part of the '...' outside of a `soma_adat`,
  just like `Summary.data.frame()`
- fixes #121
