model default scope with inq causes TypeError: Right-hand side of 'instanceof' is not callable

Nobody has claimed this yet.

## Steps to reproduce
1. Create a model including a property like:
```
"properties" : {
....
"list": {
"type": ["string"],
"index": true
}
...
}
```
2. Add "scope" to the model like:
```
"scope": {
"where": {
"list": {
"inq": ["1", "2"]
}
}
}
```

1. Add data which satisfies the scope. For example the values of list = ["2"]
2. Do a simple GET on the model via the REST API.

## Current Behavior
Exception thrown is: "TypeError: Right-hand side of 'instanceof' is not callable" in loopback-datasource-juggler\lib\utils.js on or about line 67. The offending code is this clause:
`val instanceof prop.type`

## Expected Behavior
No exception thrown and the data returned.

## Link to reproduction sandbox
reproduction sandbox forthcoming

## Additional information
If I put a try catch around the offending statement, everything works as expected.

## Related Issues

Start in loopback-datasource-juggler/lib/utils.js around the val instanceof prop.type check and reproduce the model scope using an array-of-string property with an inq filter. Trace how the property type is represented during scope evaluation. Done means the GET returns matching data without the TypeError, with a regression test for this case.
