Method hints do not work on objects returned by helpers

[Wmn]

When you use Mojo helper returning an object and try to call a method on return of the helper, IDEA does not provde method hints for the package, only SUPER::....

Example script to reproduce the issue:

#!/usr/bin/env perl

package Test1;

use feature qw(signatures);
no warnings qw(experimental::signatures);

sub new($class) {
    return bless {}, $class;
}

sub test($self) {
    return 'works';
}

1;

package main;

use feature qw/say/;
use Mojolicious::Lite -signatures;
use Test1;

helper test => sub {
    state $pkg = Test1->new
};

get '/' => sub($c) {
    say $c->test->... # <- Hint is only SUPER here, while there should be the list of methods from Test1 package
};

app->start;

Environment info:

• IntelliJ IDEA 2019.2.1 Build #IC-192.6262.58
• Plugin version 2019.2.4
• openjdk version "1.8.0_222"
• FreeBSD 13.0-CURRENT

Ok. there are two problems here:

1. Plugin don't understand definition with helper, but understand with $self->helper
2. Plugin don't understand the type of returned declaration. Meaning:

# Doesn't work
$self->helper test => sub {
    state $pkg = Test1->new
};

# Works
$self->helper test => sub {
    state $pkg = Test1->new;
    $pkg
};

Investigating

I'm afraid this can be fixed only in the next major release.
