Title: Don't return unimportables from importedSymbol.

Hardening against the symptom of SI-6745, which yielded:

wat.scala:4: error: too many arguments for constructor Predef: ()object Predef
def this() = this(0)
^
The fix for the underlying problem in that bug
has been targetted at branch 2.10.x.

Review by @paulp.

I was tempted to add a `devWarning` for this one, but before I did that I would need to check if we hit that code path under non-warnable circumstances.
