Gabriel Gonzalez 54241f88c7 Disable 1-field simplification by default (#1321)
* Disable 1-field simplification by default

This builds on top of #1315 to minimize disruption by disabling the
breaking change by default and instead requiring the user to opt in
by setting a new `collapseSingletonRecords` option to `True`.

The additional tests added to verify this also caught a bug in the
`Interpret` instance for functions, which this change also fixes.

* Change to three-valued option

... based on feedback from @sjakobi

This change the option to a three-valued option:

* `Bare`    - 1-field constructor does not include a nested record
* `Wrapped` - 1-field constructor always includes a nested record
* `Smart`   - Named fields that don't begin with `_` include a nested record

The default is `Wrapped` (for backwards compatibility), but users will
probably want to eventually switch to `Smart`

* Don't depend on `fieldModifier` for determining if a field is anonymous

... as suggested by @sjakobi
