SI-9326 Fix regression with existentials in parent types
The typechecker rewrites `p.foo` to `p.<package>.foo` if `foo`
must come from a package object. This logic was overhauled in
51745c06f3, but this caused a regression.
I reverted to the predecessor of that commit to see how things
worked before. The lookup of the name `X` bound to the existential
quantifier, but incorrectly included the prefix `test.type` in the
result of the lookup. However, the subsequent call to
`isInPackageObject` (from `makeAccessible`) returned false, so
we didn't try to rewrite `X` to `test.<package>.X`.
This commit makes a minimal fix that makes `isInPackageObject`
return false for existentials.
