In commit ec0abb0 (Fix EA-79206: Process only valid layout.xml...) we
started to drop layouts with invalid PsiFiles during resolution of
(synthetic) package fragments.
In Android Studio we run into invalid files quite often, and it seems
to be caused by a race with some invokeLater'ed code from android-ndk;
this has the side effect of now showing all the corresponding symbols
as unresolved, and the imports themselves are suggested for removal.
As a temporary fix I propose we try again to get a valid PsiFile.
