fixed bug1188

fix kind-checking in adapt: it checked tree.symbol.typeParams, which makes m[t] look like a higher-kinded type, even though it's of kind * (the symbol doesn't know about the application to t)... 

now using tree.tpe.typeParams

removed check for tree.hasSymbol (TypeTree's must also be checked,
and they don't directly have a symbol) replaced tree.symbol by
tree.tpe.symbol
