Previously, we resolved all declaration to the TYPES phase to collect their sealed inheritors
and thus not really checking lazy resolution to TYPES.
Now sealed class inheritors collection happens in separate LLFirResolveSession
The corresponding JavaSymbolProvider currently is unable to
see the `Foo` class, because under the hood it uses
`JvmDependenciesIndexImpl` which doesn't know about the corresponding
.java file because it is created for m2-module `project`
I wasn't able to fix it yet
