Avoid propagating unresolved implicits
When an implicit argument is not found, we should in any case
assume the result type of the implicit method as the type of
the tree (after reporting an error, of course). If we don't
do that, we get implicit errors on weird positions when we try
to find an implicit argument for the same tree again. This
caused a spurious error in subtyping.scala, and also caused
an additional error at the end of EqualityStrawman1.scala.
